30mm 口径贫铀穿甲弹[1]

贫铀,也称为贫化铀耗乏铀衰变铀等等,英文简写为DU,是一种主要由-238构成的物质,为核燃料制程中的的副产物,故也是一种核废料。自然界中的铀,含有约99.27%的铀-238,0.72%的铀-235,及0.0055%的铀-234,铀-235可用于核子反应堆核武器中的核裂变反应材料,但必须先将浓度提高成为浓缩铀才能使用,而在浓缩过程中排出的,铀-235浓度更低的废料部分,就称为贫铀,其中铀-235和铀-234的浓度大约只有天然铀的三分之一,放射性则约为天然铀的60%。也有部分贫铀通过再处理已使用的核燃料生产,但这类贫铀会含有铀-236。

贫铀的密度高达19.1g/cm3,与相近,可做为飞行器的配重块,或放射线疗法及工业用放射造影器材的屏蔽物,及放射性物质使用的货箱。军事上则常用做贫铀弹或装甲板材,这是因为贫铀能大幅提升穿甲强度或装甲抗度,并且贫铀弹在命中后另具有摄氏三千度的高温烧灼效果。然而使用贫铀弹可能导致潜在的长期健康威胁,而有其争议性:包括心脏等许多器官都可能受到放射性的影响。由于其微弱的放射性,贫铀被视为有毒金属,但毒性较重金属为低。贫铀粉末可能被吃、喝、或吸入人体,具有万年以上的半衰期。由贫铀弹冲击物体而爆发时产生的气溶胶,可能散布污染广大的面积,而被人吸入体内。在2003年美国伊拉克的攻击行动中,三周内估计使用了约95万颗、超过1000吨的贫铀弹,大部分都在市区。目前暂无决定性资料显示某些人的健康问题与贫铀有关联,但人工培养细胞与实验室动物的研究已发现贫铀的慢性效应造成白血病基因疾病、神经疾病等的可能性。中华民国陆军亦曾向美国采购一批坦克贫铀弹,现储放于台湾高雄市左营区军事基地弹药库中,存放之库房四壁添加以防放射性污染。

历史

编辑

1940年代,美国核武器计划开始制造浓缩铀。在往后十年,英国法国苏联也相继开展其核武器核电计划。自此,贫铀核废料以不稳定的形式储存(六氟化铀) Enriched uranium was first manufactured in the early 1940s when the United States began its nuclear weapons program. Later in the decade, Britain, France, and the Soviet Union began their nuclear weapons and nuclear power programs. It was at this time that depleted uranium was first stored as an unusable waste product (uranium hexafluoride). There was some hope that the enrichment process would be improved and fissionable isotopes of U-235 could, at some future date, be extracted from the depleted uranium. This re-enrichment recovery of the residual uranium-235 contained in the depleted uranium is no longer a matter of the future: it has been practiced for several years.[2] Also, it is possible to design civilian power-generating reactors using unenriched fuel, but only about 10% of ever built utilize that technology. Both nuclear weapons production and naval reactors require fuel containing concentrated U-235.

In the 1970s, the Pentagon reported that the Soviet military had developed armor plating for Warsaw Pact tanks that NATO ammunition could not penetrate. The Pentagon began searching for material to make denser armor-piercing projectiles. After testing various metals, ordnance researchers settled on depleted uranium.

The US and NATO militaries used DU penetrator rounds in the 1991年 波斯湾战争, the Bosnia war,[3] bombing of Serbia, and the 2003 invasion of Iraq.[4]

While clearing a decades-old Hawaii firing range in 2005, workers found depleted uranium fins from training rounds from the formerly classified Davy Crockett recoilless gun tactical battlefield nuclear delivery system from the 1960s and 1970s.[5] These training rounds had been forgotten because they were used in a highly classified program and had been fired before DU had become an item of interest, more than 20 years before the Gulf War.


Production and availability

编辑

Natural uranium metal contains about 0.71% U-235, 99.28% U-238, and about 0.0054% U-234. In order to produce enriched uranium, the process of isotope separation removes a substantial portion of the U-235 for use in nuclear power, weapons, or other uses. The remainder, depleted uranium, contains only 0.2% to 0.4% U-235. Because natural uranium begins with such a low percentage of U-235, enrichment produces large quantities of depleted uranium. For example, producing 1 kg of 5% enriched uranium requires 11.8 kg of natural uranium, and leaves about 10.8 kg of depleted uranium with only 0.3% U-235 remaining.

The Nuclear Regulatory Commission (NRC) defines depleted uranium as uranium with a percentage of the 235U isotope that is less than 0.711% by weight (see 10 CFR 40.4). The military specifications designate that the DU used by the U.S. Department of Defense (DoD) contain less than 0.3% 235U (AEPI, 1995). In actuality, DoD uses only DU that contains approximately 0.2% 235U (AEPI, 1995).

Depleted Uranium is also produced by recycling 'spent' nuclear fuel,[6] in which case it contains traces of Pu and Np[7] and has therefore been called 'dirty DU'[8] although the quantities are so small that they are considered to be not of serious radiological significance (even) by ECRR.[9]

六氟化铀

Hexafluoride tank leaking

约95%的贫铀是以晶体状形式的六氟化铀,储存在钢制容器内 of the depleted uranium produced is stored as uranium hexafluoride, a crystalline solid, (D)UF6, in steel cylinders in open air storage yards close to enrichment plants. Each cylinder holds up to 12.7 tonnes (or 14 short tons) of UF6. In the U.S. 560,000 tonnes of depleted UF6 had accumulated by 1993. In 2008, 686,500 tonnes in 57,122 storage cylinders were located near Portsmouth, Ohio and Paducah, Kentucky.[10][11]

The storage of DUF6 presents environmental, health, and safety risks because of its chemical instability. When UF6 is exposed to water vapor in the air, it reacts with the moisture to produce UO2F2 (uranyl fluoride), a solid, and HF (hydrogen fluoride), a gas, both of which are highly soluble and toxic. The uranyl fluoride solid acts to plug the leak, limiting further escape of depleted UF6. Release of the hydrogen fluoride gas to the atmosphere is also slowed by the plug formation.[12] Storage cylinders are regularly inspected for signs of corrosion and leaks, and are repainted and repaired as necessary.[13]

A tenfold jump in uranium prices has transformed approximately one-third of the U.S. depleted uranium inventory into an asset worth $7.6 billion, assuming DOE re-enriches the tails. This estimate is based on February 2008 market price for uranium and enrichment services, and DOE's access to sufficient uranium enrichment capacity.[14]

There have been several accidents involving uranium hexafluoride in the United States, including one in which 31 workers were exposed to a cloud of UF6 and its reaction products. Though some of the more highly exposed workers showed evidence of short-term kidney damage (e.g., protein in the urine), none of these workers had lasting kidney toxicity from the uranium exposure.[15] The U.S. government has been converting DUF6 to solid uranium oxides for use or disposal.[16] Such disposal of the entire DUF6 inventory could cost anywhere from $15 million to $450 million.[17]

Depleted uranium is very dense; at 19,050 kg/m³, it is 1.67 times as dense as lead, only slightly less dense than tungsten and gold, and 84% as dense as osmium or iridium, which are the densest known substances under standard (i.e., Earth-surface) pressures. Consequently a DU projectile of given mass has a smaller diameter than an equivalent lead projectile, with less aerodynamic drag and deeper penetration due to a higher pressure at point of impact. DU projectile ordnance is often inherently incendiary because of its pyrophoric property.[18]

装甲板

因为其高密度,贫铀用以制造坦克装甲Because of its high density, depleted uranium can also be used in tank armor, sandwiched between sheets of steel armor plate. For instance, some late-production M1A1HA and M1A2 Abrams tanks built after 1998 have DU reinforcement as part of the armor plating in the front of the hull and the front of the turret, and there is a program to upgrade the rest (see Chobham armor).

弹药

Most military use of depleted uranium has been as 30 mm caliber ordnance, primarily the 30 mm PGU-14/B armour-piercing incendiary round from the GAU-8 Avenger cannon of the A-10 Thunderbolt II used by the United States Air Force. 25 mm DU rounds have been used in the M242 gun mounted on the U.S. Army's Bradley Fighting Vehicle and the Marine Corp's LAV-25.

The U.S. Marine Corps uses DU in the 25 mm PGU-20 round fired by the GAU-12 Equalizer cannon of the AV-8B Harrier, and also in the 20 mm M197 gun mounted on AH-1 Cobra helicopter gunships. The United States Navy's Phalanx CIWS's M61 Vulcan Gatling gun used 20 mm armor-piercing penetrator rounds with discarding plastic sabots made using depleted uranium, later changed to tungsten.

Another use of depleted uranium is in kinetic energy penetrators, anti-armor rounds such as the 120 mm sabot rounds fired from the M1A1 and M1A2 Abrams.[19] Kinetic energy penetrator rounds consist of a long, relatively thin penetrator surrounded by a discarding sabot. Staballoys are metal alloys of depleted uranium with a very small proportion of other metals, usually titanium or molybdenum. One formulation has a composition of 99.25% by mass of depleted uranium and 0.75% by mass of titanium. Staballoys are approximately 1.67 times as dense as lead and are designed for use in kinetic energy penetrator armor-piercing ammunition. The US Army uses DU in an alloy with around 3.5% titanium.

According to 2005 research,[20] at least some of the most promising tungsten alloys that have been considered as replacement for depleted uranium in penetrator ammunitions, such as tungsten-cobalt or tungsten-nickel-cobalt alloys, also possess extreme carcinogenic properties, which by far exceed those (confirmed or suspected) of depleted uranium itself: 100% of rats implanted with a pellet of such alloys developed lethal rhabdomyosarcoma within a few weeks.

Depleted uranium is favored for the penetrator because it is self-sharpening and pyrophoric.[18] On impact with a hard target, such as an armored vehicle, the nose of the rod fractures in such a way that it remains sharp. The impact and subsequent release of heat energy causes it to disintegrate to dust and burn when it reaches air because of its pyrophoric properties.[18] When a DU penetrator reaches the interior of an armored vehicle it catches fire, often igniting ammunition and fuel, killing the crew and possibly causing the vehicle to explode. DU is used by the U.S. Army in 120 mm or 105 mm cannons employed on the M1 Abrams tank. The Russian military has used DU ammunition in tank main gun ammunition since the late 1970s, mostly for the 115 mm guns in the T-62 tank and the 125 mm guns in the T-64, T-72, T-80, and T-90 tanks.

The DU content in various ammunition is 180 g in 20 mm projectiles, 200 g in 25 mm ones, 280 g in 30 mm, 3.5 kg in 105 mm, and 4.5 kg in 120 mm penetrators. DU was used during the mid-1990s in the U.S. to make hand grenades, cluster bombs, and land mines, but those applications have been discontinued, according to Alliant Techsystems.[来源请求] The US Navy used DU in its 20 mm Phalanx CIWS guns, but switched in the late 1990s to armor-piercing tungsten.

It is thought that between 17 and 20 countries have weapons incorporating depleted uranium in their arsenals. They include the U.S., the UK, France, Russia, China, India, Turkey, Saudi Arabia, Israel, Bahrain, Egypt, Kuwait, Pakistan, Thailand, Iraq and Taiwan.[来源请求] Iran also has performed wide research on DU penetrators since 2001[来源请求]. DU ammunition is manufactured in 18 countries. Only the US and the UK have acknowledged using DU weapons.[21]

In a three-week period of conflict in Iraq during 2003 it was estimated that over 1000 tons of depleted uranium munitions were used.[22]

武器使用合法性

编辑

1996年,In 1996 the International Court of Justice (ICJ) gave an advisory opinion on the "legality of the threat or use of nuclear weapons".[23] This made it clear, in paragraphs 54, 55 and 56, that international law on poisonous weapons—the Second Hague Declaration of 29 July 1899, Hague Convention IV of 18 October 1907 and the Geneva Protocol of 17 June 1925—did not cover nuclear weapons, because their prime or exclusive use was not to poison or asphyxiate. This ICJ opinion was about nuclear weapons, but the sentence "The terms have been understood, in the practice of States, in their ordinary sense as covering weapons whose prime, or even exclusive, effect is to poison or asphyxiate," also removes depleted uranium weaponry from coverage by the same treaties as their primary use is not to poison or asphyxiate, but to destroy materiel and kill soldiers through kinetic energy.

The Sub-Commission on Prevention of Discrimination and Protection of Minorities of the United Nations Human Rights Commission,[24] passed two motions[25] — the first in 1996[26] and the second in 1997.[27] They listed weapons of mass destruction, or weapons with indiscriminate effect, or of a nature to cause superfluous injury or unnecessary suffering and urged all states to curb the production and the spread of such weapons. Included in the list was weaponry containing depleted uranium. The committee authorized a working paper, in the context of human rights and humanitarian norms, of the weapons.

The requested UN working paper was delivered in 2002[28] by Y. K. J. Yeung Sik Yuen in accordance with Sub-Commission on the Promotion and Protection of Human Rights resolution 2001/36. He argues that the use of DU in weapons, along with the other weapons listed by the Sub‑Commission, may breach one or more of the following treaties: the Universal Declaration of Human Rights, the Charter of the United Nations, the Genocide Convention, the United Nations Convention Against Torture, the Geneva Conventions including Protocol I, the Convention on Conventional Weapons of 1980, and the Chemical Weapons Convention. Yeung Sik Yuen writes in Paragraph 133 under the title "Legal compliance of weapons containing DU as a new weapon":

Annex II to the Convention on the Physical Protection of Nuclear Material 1980 (which became operative on 8 February 1997) classifies DU as a category II nuclear material. Storage and transport rules are set down for that category which indicates that DU is considered sufficiently "hot" and dangerous to warrant these protections. But since weapons containing DU are relatively new weapons no treaty exists yet to regulate, limit or prohibit its use. The legality or illegality of DU weapons must therefore be tested by recourse to the general rules governing the use of weapons under humanitarian and human rights law which have already been analysed in Part I of this paper, and more particularly at paragraph 35 which states that parties to Protocol I to the Geneva Conventions of 1949 have an obligation to ascertain that new weapons do not violate the laws and customs of war or any other international law. As mentioned, the International Court of Justice considers this rule binding customary humanitarian law.

Louise Arbour, chief prosecutor for the International Criminal Tribunal for the Former Yugoslavia led a committee of staff lawyers to investigate possible treaty prohibitions against the use of DU in weapons. Their findings were that:[29]

There is no specific treaty ban on the use of DU projectiles. There is a developing scientific debate and concern expressed regarding the impact of the use of such projectiles and it is possible that, in future, there will be a consensus view in international legal circles that use of such projectiles violate general principles of the law applicable to use of weapons in armed conflict. No such consensus exists at present.[30]

Requests for a moratorium on military use

编辑

Some states and the International Coalition to Ban Uranium Weapons, a coalition of more than 155 non-governmental organizations, have asked for a ban on the production and military use of depleted uranium weapons.[31]

The European Parliament has repeatedly passed resolutions requesting an immediate moratorium on the further use of depleted uranium ammunition,[32][33] but France and Britain – the only EU states that are permanent members of the United Nations Security Council – have consistently rejected calls for a ban,[34] maintaining that its use continues to be legal, and that the health risks are unsubstantiated.[35]

In 2007 France, Britain, the Netherlands, and the Czech Republic voted against a United Nations General Assembly resolution to hold a debate in 2009 about the effects of the use of armaments and ammunitions containing depleted uranium. All other European Union nations voted in favour or abstained.[36] The ambassador from the Netherlands explained his negative vote as being due to the reference in the preamble to the resolution "to potential harmful effects of the use of depleted uranium munitions on human health and the environment [which] cannot, in our view, be supported by conclusive scientific studies conducted by relevant international organizations."[37] None of the other permanent members of the United Nations Security Council supported the resolution as China was absent for the vote, Russia abstained and the United States voted against the resolution.[36]

In September 2008, and in response to the 2007 General Assembly resolution, the UN Secretary General published the views of 15 states alongside those of the International Atomic Energy Agency (IAEA) and World Health Organization (WHO). The IAEA and WHO evidence differed little from previous statements on the issue.[38] The report was largely split between states concerned about depleted uranium's use, such as Finland, Cuba, Japan, Serbia, Argentina, and predominantly NATO members, who do not consider the use of depleted uranium munitions problematic.[38]

In December 2008, 141 states supported a resolution requesting that three UN agencies: United Nations Environment Programme (UNEP), WHO and IAEA update their research on the impact of uranium munitions by late 2010 – to coincide with the General Assembly's 65th Session, four voted against, 34 abstained and 13 were absent[39] As before Britain and France voted against the resolution. All other European Union nations voted in favour or abstained: the Netherlands, which voted against a resolution in 2007, voted in favour, as did Finland and Norway, both of which had abstained in 2007, while the Czech Republic, which voted against the resolution in 2007, abstained. The two other states that voted against the resolution were Israel and the United States (both of which voted against in 2007), while as before China was absent for the vote, and Russia abstained.[39]

2009年6月21日,比利时成为首个禁止“含有贫铀或其他工业生产铀金属的惰性弹药或装甲”的国家[40]。 The move followed a unanimous parliamentary vote on the issue on 22 March 2007. The text of the 2007 law allowed for two years to pass until it came into force.[41] In April 2009, the Belgian Senate voted unanimously to restrict investments by Belgian banks into the manufacturers of depleted uranium weapons.[42]

In September 2009 the Latin American Parliament passed a resolution calling for a regional moratorium on the use, production and procurement of uranium weapons. It also called on the Parlatino's members to work towards an international uranium weapons treaty.[43]

In December 2010 the UN General Assembly passed a resolution calling on users of depleted uranium to hand over quantitative and geographical data on their use, to the relevant authorities of affected states when requested to do so. The resolution passed by 148 votes to four, with 30 abstentions. Five states that abstained on previous resolutions in 2007 and 2008 voted in favour – Belgium, Bosnia & Herzegovina, Greece, Luxembourg and Slovenia, and no former supporters changed position. The UK, US, Israel and France voted against.[44]

In April 2011 the Congress of Costa Rica passed a law prohibiting uranium weapons in its territories, becoming the second country in the world to do so.[45] In November 2010 the Irish Senate passed a bill seeking to outlaw depleted uranium weapons,[46] but it lapsed before approval by the Dáil[47]

In December 2012 the UN General Assembly passed a fourth resolution on depleted uranium. The text of 67/36 built on previous texts and recalled the position of the UN Environment Programme, which had called for a precautionary approach to the use of DU due to ongoing uncertainties over its long-term environmental behaviour. The resolution was supported by 155 states, with 27 abstentions and, as with previous texts, the US, UK, France and Israel opposed.

Depleted uranium has a very high density and is primarily used as shielding material for other radioactive material, and as ballast. Examples include sailboat keels, as counterweights and as shielding in industrial radiography cameras.

Industrial radiography cameras include a very high activity gamma radiation source (typically Ir-192 with an activity above 10 TBq). Depleted uranium is often used in the cameras as a shield to protect individuals from the gamma source. Typically the uranium shield is supported and enclosed in polyurethane foam for thermal, mechanical and oxidation protection.[48]

Consumer product uses have included incorporation into dental porcelain, used for false teeth to simulate the fluorescence of natural teeth, and uranium-bearing reagents used in chemistry laboratories (e.g. uranyl acetate, used in analytical chemistry and as a stain in electron microscopy). Uranium (both depleted uranium and natural uranium) was widely used as a coloring matter for porcelain and glass in the 19th and early-to-mid-20th century. The practice was largely discontinued in the late 20th century. In 1999 concentrations of 10% depleted uranium were being used in "jaune no.17" a yellow enamel powder that was being produced in France by Cristallerie de Saint-Paul, a manufacturer of enamel pigments. The depleted uranium used in the powder was sold by Cogéma's Pierrelatte facility. In February 2000, Cogema discontinued the sale of depleted uranium to producers of enamel and glass.[49]

Aircraft that contain depleted uranium trim weights (such as the Boeing 747–100) may contain between 400 to 1,500 kg of DU. This application is controversial because the DU may enter the environment if the aircraft were to crash. The metal can also oxidize to a fine powder in a fire. Its use has been phased out in many newer aircraft. Boeing and McDonnell-Douglas discontinued using DU counterweights in the 1980s. Depleted uranium was released during the crash of El Al Flight 1862 on 4 October 1992, in which 152 kg was lost, but an extensive study concluded that there was no evidence to link depleted uranium from the plane to any health problems.[50] Counterweights manufactured with cadmium plating are considered non-hazardous while the plating is intact.[51]

美国核管会许可证

编辑

美国核管会(NRC) regulations at 10 CFR 40.25 establish a general license for the use of depleted uranium contained in industrial products or devices for mass-volume applications. This general license allows anyone to possess or use depleted uranium for authorized purposes. Generally, a registration form is required, along with a commitment to not abandon the material. Agreement states may have similar, or more stringent, regulations.

尽管事实上贫铀比其他重金属诸如毒性较低,但因具有弱放射性并且剧毒,贫铀仍会影响大脑、肾脏、肝脏、心脏以及其他系统功能正常运作。[54]although less toxic than other heavy metals such as arsenic and mercury.[55] It is weakly radioactive but is 'persistently' so because of its long half-life. The Agency for Toxic Substances and Disease Registry states that: "to be exposed to radiation from uranium, you have to eat, drink, or breathe it, or get it on your skin."[56] If DU particles do enter an individual, the type of danger presented—toxic vs. radiological—and the organ most likely to be affected depend on the solubility of the particles.[57]

In military conflicts involving DU munitions, the major concern is inhalation of DU particles in aerosols arising from the impacts of DU-enhanced projectiles with their targets.[57] When depleted uranium munitions penetrate armor or burn, they create depleted uranium oxides in the form of dust that can be inhaled or contaminate wounds. The Institute of Nuclear Technology-Radiation Protection of Attiki, Greece, has noted that "the aerosol produced during impact and combustion of depleted uranium munitions can potentially contaminate wide areas around the impact sites or can be inhaled by civilians and military personnel."[58] The utilisation of DU in incendiary ammunition is controversial because of potential adverse health effects and its release into the environment.[59][60][61][62][63][64]

The U.S. Department of Defense claims that no human cancer of any type has been seen as a result of exposure to either natural or depleted uranium.[65] Militaries have long had risk-reduction procedures for their troops to follow,[66] and studies are in consistent agreement that veterans who used DU-enhanced munitions have not suffered, so far, from an increased risk of cancer (see the Gulf War and Balkans sections below). The effects of DU on civilian populations are, however, a topic of intense and ongoing controversy.

As early as 1997, British Army doctors warned the British MoD (Ministry of Defence) that exposure to depleted uranium increased the risk of developing lung, lymph and brain cancer, and recommended a series of safety precautions.[67] According to a report issued summarizing the advice of the doctors, "Inhalation of insoluble uranium dioxide dust will lead to accumulation in the lungs with very slow clearance—if any. … Although chemical toxicity is low, there may be localised radiation damage of the lung leading to cancer." The report warns that "All personnel … should be aware that uranium dust inhalation carries a long-term risk … [the dust] has been shown to increase the risks of developing lung, lymph and brain cancers."[67] In 2003, the Royal Society called, again, for urgent attention to be paid to the possible health and environmental impact of depleted uranium, and added its backing to the United Nations Environment Programme's call for a scientific assessment of sites struck with depleted uranium.[68] In early 2004, the UK Pensions Appeal Tribunal Service attributed birth defect claims from a February 1991 Gulf War combat veteran to depleted uranium poisoning.[69][70] Also, a 2005 epidemiology review concluded: "In aggregate the human epidemiological evidence is consistent with increased risk of birth defects in offspring of persons exposed to DU."[71] Studies using cultured cells and laboratory rodents continue to suggest the possibility of leukemogenic, genetic, reproductive, and neurological effects from chronic exposure.[72]

The chemical toxicity of depleted uranium is about a million times greater in vitro than its radiological hazard,[73] with the kidney considered to be the main target organ.[74] Health effects of DU are determined by factors such as the extent of exposure and whether it was internal or external. Three main pathways exist by which internalization of uranium may occur: inhalation, ingestion, and embedded fragments or shrapnel contamination.[75] Properties such as phase (e.g. particulate or gaseous), oxidation state (e.g. metallic or ceramic), and the solubility of uranium and its compounds influence their absorption, distribution, translocation, elimination and the resulting toxicity. For example, metallic uranium is less toxic compared to hexavalent uranium(VI) uranyl compounds such as uranium trioxide.[76][77]

Uranium is pyrophoric when finely divided.[18] It will corrode under the influence of air and water producing insoluble uranium(IV) and soluble uranium (VI) salts. Soluble uranium salts are toxic. Uranium slowly accumulates in several organs, such as the liver, spleen, and kidneys. The World Health Organization has established a daily "tolerated intake" of soluble uranium salts for the general public of 0.5 µg/kg body weight, or 35 µg for a 70 kg adult.

Epidemiological studies and toxicological tests on laboratory animals point to it as being immunotoxic,[78] teratogenic,[79][80] neurotoxic,[81] with carcinogenic and leukemogenic potential.[82] A 2005 report by epidemiologists concluded: "the human epidemiological evidence is consistent with increased risk of birth defects in offspring of persons exposed to DU."[71]

Early studies of depleted uranium aerosol exposure assumed that uranium combustion product particles would quickly settle out of the air[83] and thus could not affect populations more than a few kilometers from target areas,[84] and that such particles, if inhaled, would remain undissolved in the lung for a great length of time and thus could be detected in urine.[85] Violently burning uranium droplets produce a gaseous vapor comprising about half of the uranium in their original mass.[86] Uranyl ion contamination in uranium oxides has been detected in the residue of DU munitions fires.[87][88]

Approximately 90 micrograms of natural uranium, on average, exist in the human body as a result of normal intake of water, food and air. Most is in the skeleton. The biochemistry of depleted uranium is the same as natural uranium.

The primary radiation danger from depleted uranium is due to alpha particles, which do not travel far through air, and do not penetrate clothing. Thus, the primary concern is internal exposure, due to inhalation, ingestion or shrapnel contamination. Available evidence suggests that this risk is small relative to the chemical hazard.[73]

Surveying the veteran-related evidence pertaining to the Gulf War, a 2001 editorial in the BMJ concluded it was not possible to justify claims of radiation-induced lung cancer and leukaemia in veterans of that conflict.[89] While agreeing with the editorial's conclusion, a reply noted that its finding in the negative was guaranteed, given that "global dose estimates or results of mathematical modelling are too inaccurate to be used as dose values for an individual veteran", and that, as of April 2001, no practical method of measuring the expected small doses that each individual veteran would receive had been suggested.[90] The author of the reply, a radiation scientist, went on to suggest a method that had been used several times before, including after the 1986 Chernobyl accident.[90] Despite the widespread use of DU in the Iraq War, at least a year after the conflict began, testing for UK troops was still only in the discussion phase.[91]

The Royal Society DU Working Group concluded in 2002 that there were "very low" health risks associated with the use of depleted uranium, though also ventured that, "[i]n extreme conditions and under worst-case assumptions" lung and kidney damage could occur, and that in "worst-case scenarios high local levels of uranium could occur in food or water that could have adverse effects on the kidney."[92] In 2003, the Royal Society issued another urgent call to investigate the actual health and environmental impact of depleted uranium.[68] The same year, a cohort study of Gulf War veterans found no elevated risks of cancer generally, nor of any specific cancers in particular, though recommended follow up studies.[93]

According to the World Health Organization, a radiation dose from it would be about 60% of that from purified natural uranium with the same mass; the radiological dangers are lower due to its longer half-life and the removal of the more radioactive isotopes. However, in a matter of a month or so, depleted uranium generates amounts of thorium-234 and protactinium-234, which emit beta particles at almost the same rate as that of the alpha particles from the uranium-238.

Gulf War syndrome and soldier complaints

Since 1991, the year the Gulf War ended, veterans and their families voiced concern about subsequent health problems.[95] In 1999, assessment of the first 1,000 veterans involved in the Ministry of Defence's Gulf War medical assessment programme found "no evidence" of a single illness, physical or mental, that would explain the pattern of symptoms observed in the group.[96] Nevertheless, in 1999, MEDACT petitioned for the WHO to conduct an investigation into illnesses in veterans and Iraqi civilians.[97] A major 2006 review of peer-reviewed literature by a US Institute of Medicine committee concluded that, "[b]ecause the symptoms vary greatly among individuals," they do not point to a syndrome unique to Gulf War veterans, though their report conceded that the lack of objective pre-deployment health data meant definitive conclusions were effectively impossible.[98] Simon Wessely praised the IOM's review, and noted that despite its central conclusion that no novel syndrome existed, its other findings made it "equally clear that service in the Gulf war did aversely affect health in some personnel."[99] Aside from the lack of baseline data to guide analysis of the veterans' postwar health, because no detailed health screening was carried out when the veterans entered service, another major stumbling block with some studies, like the thousand-veteran one, is that the subjects are self selected, rather than a random sample, making general conclusions impossible.[100]

Increased rates of immune system disorders and other wide-ranging symptoms, including chronic pain, fatigue and memory loss, have been reported in over one quarter of combat veterans of the 1991 Gulf War.[101] Combustion products[102] from depleted uranium munitions are being considered as one of the potential causes by the Research Advisory Committee on Gulf War Veterans' Illnesses, as DU was used in 30 mm and smaller caliber machine-gun bullets on a large scale for the first time in the Gulf War. Veterans of the conflicts in the Persian Gulf, Bosnia and Kosovo have been found to have up to 14 times the usual level of chromosome abnormalities in their genes.[103][104] Serum-soluble genotoxic teratogens produce congenital disorders, and in white blood cells causes immune system damage.[105]

Human epidemiological evidence is consistent with increased risk of birth defects in the offspring of persons exposed to DU.[71] A 2001 study of 15,000 February 1991 U.S. Gulf War combat veterans and 15,000 control veterans found that the Gulf War veterans were 1.8 (fathers) to 2.8 (mothers) times more likely to have children with birth defects.[106] After examination of children's medical records two years later, the birth defect rate increased by more than 20%:

Dr. Kang found that male Gulf War veterans reported having infants with likely birth defects at twice the rate of non-veterans. Furthermore, female Gulf War veterans were almost three times more likely to report children with birth defects than their non-Gulf counterparts. The numbers changed somewhat with medical records verification. However, Dr. Kang and his colleagues concluded that the risk of birth defects in children of deployed male veterans still was about 2.2 times that of non-deployed veterans.[107]

In early 2004, the UK Pensions Appeal Tribunal Service attributed birth defect claims from a February 1991 Gulf War combat veteran to depleted uranium poisoning.[108][109] Looking at the risk of children of UK Gulf War veterans suffering genetic diseases such as congenital malformations, commonly called "birth defects", one study found that the overall risk of any malformation was 50% higher in Gulf War veterans as compared to other veterans.[110]

The U.S. Army has commissioned ongoing research into potential risks of depleted uranium and other projectile weapon materials like tungsten, which the U.S. Navy has used in place of DU since 1993. Studies by the U.S. Armed Forces Radiobiology Research Institute conclude that moderate exposures to either depleted uranium or uranium present a significant toxicological threat.[111]

In 2003 Professor Brian Spratt FRS, chairman of the Royal Society's working group on depleted uranium, said: "The question of who carries out the initial monitoring and clean-up is a political rather than scientific question," and "the coalition needs to acknowledge that depleted uranium is a potential hazard and make in-roads into tackling it by being open about where and how much depleted uranium has been deployed."[22]

A 2008 review of all relevant articles appearing in the peer-reviewed journals on MEDLINE through to the end of 2007, including multiple cohort studies of veterans, found no consistent evidence of excess risks of neoplasms that could have some link to DU, and that "[t]he overall incidence of cancers is not increased in the cohort studies of Gulf war and Balkans veterans".[112]

Though a more comprehensive assessment is possible, a 2011 update on a cancer scare regarding Italian soldiers who had served in the Balkans found lower than expected incidence rates for all cancers, a finding "consistent with lacking evidence of an increased cancer incidence among troops of other countries deployed in the areas of Iraq, Bosnia, and Kosovo, where armour-penetrating depleted uranium shells have been used."[113]

One particular subgroup of veterans that may be at higher risk comprises those who have internally retained fragments of DU from shrapnel wounds. A laboratory study on rats produced by the Armed Forces Radiobiology Research Institute showed that, after a study period of 6 months, rats treated with depleted uranium coming from implanted pellets, comparable to the average levels in the urine of Desert Storm veterans with retained DU fragments, had developed a significant tendency to lose weight with respect to the control group.[114]

Substantial amounts of uranium were accumulating in their brains and central nervous systems, and showed a significant reduction of neuronal activity in the hippocampus in response to external stimuli. The conclusions of the study show that brain damage from chronic uranium intoxication is possible at lower doses than previously thought. Results from computer-based neurocognitive tests performed in 1997 showed an association between uranium in the urine and "problematic performance on automated tests assessing performance efficiency and accuracy."[115]

Iraqi population

编辑

Since 2001, medical personnel at the Basra hospital in southern Iraq have reported a sharp increase in the incidence of child leukemia and genetic malformation among babies born in the decade following the Gulf War. Iraqi doctors attributed these malformations to possible long-term effects of DU, an opinion that was echoed by several newspapers.[63][116][117][118] In 2004, Iraq had the highest mortality rate due to leukemia of any country.[119] In 2003, the Royal Society called for Western militaries to disclose where and how much DU they had used in Iraq so that rigorous, and hopefully conclusive, studies could be undertaken out in affected areas.[120] The International Coalition to Ban Uranium Weapons (ICBUW) likewise urged that an epidemiological study be made in the Basra region, as asked for by Iraqi doctors,[121] but no peer-reviewed study has yet been undertaken in Basra.

A medical survey, "Cancer, Infant Mortality and Birth Sex Ratio in Fallujah, Iraq 2005–2009" published in July 2010, states that the "Increase in cancer and birth defects…are alarmingly high" and that infant mortality 2009/2010 has reached 13.6%. The group compares the dramatic increase, five years after the actual war 2004, or exposure, with the lymphoma Italian peacekeepers[122] developed after the Balkan wars, and the increased cancer risk in certain parts of Sweden due to the Chernobyl fallout. The origin and time of introduction of the carcinogenic agent causing the genetic stress, the group will address in a separate report.[123] Iraqi doctors compare the cancer rates (projected to touch 50% in some areas) with the cancer epidemic after the nuclear strikes against Japan, with one US military physicist describing the use of DU shells as "a form of nuclear warfare."[124]

Four studies in the second half of 2012—one of which described the people of Fallujah as having "the highest rate of genetic damage in any population ever studied"—renewed calls for the US and UK to investigate the possible links between their brutal military assault on the city in 2004 and the explosion in hideous deformities, cancers, and other serious health problems.[125][126]

The Balkans

编辑
 
Sites in Kosovo and southern Central Serbia where NATO aviation used depleted uranium during the 1999 Kosovo War.

In 2001, doctors at the Serb-run hospital in Kosovska Mitrovica say the number of patients suffering from malignant diseases has increased by 200% since 1998.[127] In the same year, the World Health Organization reported that data from Kosovo was inconclusive and called for further studies.[128]

A 2003 study by the United Nations Environment Programme (UNEP) in Bosnia and Herzegovina stated that low levels of contaminate were found in drinking water and air particulate at DU penetrator impact points. The levels were stated as not a cause for alarm. Yet, Pekka Haavisto, chairman of the UNEP DU projects stated, "The findings of this study stress again the importance of appropriate clean-up and civil protection measures in a post-conflict situation."[129]

A team of Italian scientists from the University of Siena reported in 2005 that although DU was "clearly" added to the soil in the study area, "the phenomenon was very limited spatially and the total uranium concentrations fell within the natural range of the element in soils. Moreover, the absolute uranium concentrations indicate that there was no contamination of the earthworm species studied."[130]

Contamination as a result of the Afghan War

编辑

The Canadian Uranium Medical Research Centre obtained urine samples from bombed civilian areas in Jalalabad that showed concentrations of 80–400 ng/L of undepleted uranium, far higher than the typical concentration in the British population of ~5 ng/L.[131]

Studies indicating negligible effects

编辑

Studies in 2005 and earlier have concluded that DU ammunition has no measurable detrimental health effects.

A 1999 literature review conducted by the Rand Corporation stated: "No evidence is documented in the literature of cancer or any other negative health effect related to the radiation received from exposure to depleted or natural uranium, whether inhaled or ingested, even at very high doses,"[132] and a RAND report authored by the U.S. Defense department undersecretary charged with evaluating DU hazards considered the debate to be more political than scientific.[133]

A 2001 oncology study concluded that "the present scientific consensus is that DU exposure to humans, in locations where DU ammunition was deployed, is very unlikely to give rise to cancer induction".[134] 前任北约秘书长罗拔臣爵士在2001年表示:“目前的医学对于品有危害的意见是一致的,贫铀的危险性是极其有限的、并且是在特定的情况下”。[135]

A 2002 study from the Australian defense ministry concluded that "there has been no established increase in mortality or morbidity in workers exposed to uranium in uranium processing industries... studies of Gulf War veterans show that, in those who have retained fragments of depleted uranium following combat related injury, it has been possible to detect elevated urinary uranium levels, but no kidney toxicity or other adverse health effects related to depleted uranium after a decade of follow-up."[136] Pier Roberto Danesi, then-director of the International Atomic Energy Agency (IAEA) Seibersdorf +Laboratory, stated in 2002 that "There is a consensus now that DU does not represent a health threat".[137]

国际原子能机构在2003年指出,The IAEA reported in 2003 that, "based on credible scientific evidence, there is no proven link between DU exposure and increases in human cancers or other significant health or environmental impacts," although "Like other heavy metals, DU is potentially poisonous. In sufficient amounts, if DU is ingested or inhaled it can be harmful because of its chemical toxicity. High concentration could cause kidney damage." The IAEA concluded that while depleted uranium is a potential carcinogen, there is no evidence that it has been carcinogenic in humans.[138]

A 2005 study by Sandia National Laboratories' Al Marshall used mathematical models to analyze potential health effects associated with accidental exposure to depleted uranium during the 1991 Gulf War. Marshall's study concluded that the reports of cancer risks from DU exposure are not supported by his analysis nor by veteran medical statistics. Marshall also examined possible genetic effects due to radiation from depleted uranium.[139] Chemical effects, including potential reproductive issues, associated with depleted uranium exposure were discussed in some detail in a subsequent journal paper.[140]

军事行动所造成的大地污染

编辑

Elevated radiation levels consistent with very low level atmospheric depleted uranium contamination have been found in air samples taken by the UK Atomic Weapons Establishment at several monitoring sites in Britain. These elevated readings appear to coincide with Operation Anaconda in Afghanistan, and the Shock and Awe bombing campaign at the start of the Second Gulf War.[141][142]

其他受污染案例

编辑

1992年10月4日,以色列航空一架波音747-258F货机在执飞1862航班时,失控撞进阿姆斯特丹郊外的一个住宅区。当地居民以及救援人员怀疑因航机坠毁引起不明有毒物质释出 Local residents and rescue workers complained of various unexplained health issues which were being attributed to the release of hazardous materials during the crash and subsequent fires. Authorities conducted an epidemiological study in 2000 of those believed to be affected by the accident. The study concluded that there was no evidence to link depleted uranium (used as counterbalance weights on the elevators of the plane) to any of the reported health complaints.[50]

Safety and environmental issues

编辑

About 95% of the depleted uranium produced until now is stored as uranium hexafluoride, (D)UF6, in steel cylinders in open air yards close to enrichment plants. Each cylinder contains up to 12.7 tonnes (or 14 US tons) of UF6. In the U.S. alone, 560,000 tonnes of depleted UF6 had accumulated by 1993. In 2005, 686,500 tonnes in 57,122 storage cylinders were located near Portsmouth, Ohio, Oak Ridge, Tennessee, and Paducah, Kentucky.,[143][144] The long-term storage of DUF6 presents environmental, health, and safety risks because of its chemical instability. When UF6 is exposed to moist air, it reacts with the water in the air and produces UO2F2 (uranyl fluoride) and HF (hydrogen fluoride), both of which are highly soluble and toxic. Storage cylinders must be regularly inspected for signs of corrosion and leaks. The estimated lifetime of the steel cylinders is measured in decades.[145]

There have been several accidents involving uranium hexafluoride in the United States.[146] The vulnerability of DUF6 storage cylinders to terrorist attack is apparently not the subject of public reports. However, the U.S. government has been converting DUF6 to solid uranium oxides for disposal.[147] Disposing of the whole DUF6 inventory could cost anywhere from 15 to 450 million dollars.[148]

  90. ^ 90.0 90.1 Mould 2001.
    Mould's suggestion was electron paramagnetic resonance dosimetry using tooth enamel. He also wrote that the US National Institute of Standards and Technology was able, using this method, to measure doses as low as 20 mSv, and that, if it were asked to, the NIST would be able to get involved, meaning at least one centre could help undertake a screening programme for veterans.
  91. ^ Greenberg et al. 2004, which found that perhaps a quarter of all UK troops would have been interested in undergoing DU-related monitoring, although "the desire for DU screening is more closely linked to current health status rather than plausible exposure to DU."

    Confusingly, Moszynski 2003 reports that "testing is now available to all troops that served in Iraq", and does not say if this is testing à la Mould.

  92. ^ The study is mentioned by Patel 2006.
    According to Patel, "[t]he majority evidence and expert opinion on the lack of a clear association between depleted uranium are quite consistent". Similarly Murphy, Greenberg & Bland 2009: "[T]here is now a large body of evidence to suggest that, whatever the cause of the ill‐health experienced by Gulf War veterans, neither DU nor vaccinations are likely to have caused them."

    The Working Group study he mentions is Royal Society DU Working Group 2002b, which is a summary of the second part of the Working Group's look at the health effects of DU: Part 1: RSDUWG 2001; Part 2: RSDUWG 2002a.

  93. ^ Macfarlane et al. 2003: "There is no current excess risk of cancer overall nor of site specific cancers in Gulf war veterans. Specific exposures during deployment have not resulted in a subsequent increased risk of cancer. The long latent period for cancer, however, necessitates the continued follow up of these cohorts."

  95. ^ Murphy 1999.
  96. ^ Coker et al. 1999: "As the veterans assessed by the programme were all self selected, the prevalence of illness in Gulf war veterans cannot be determined from this study. Furthermore, it is not known whether the veterans in this study were representative of sick veterans as a group."
    To recapitulate using Murphy 1999: "[T]hough Gulf War veterans' illnesses are real and sometimes disabling, they do not seem to constitute a unique illness."
  97. ^ Stott & Holdstock 1999.
  98. ^ Charatan 2006. The quote is of Lynn Goldman, who chaired the IOM committee that carried out the review.

    Iversen, Chalder & Wessely 2007 notes that "despite clear evidence of an increase in symptom burden and a decrease in well being" among Gulf War veterans, "exhaustive clinical and laboratory based scientific research has failed to document many reproducible biomedical abnormalities in this group. Likewise, there has been no evidence of an increase in disease related mortality."

  102. ^ Murphy, Greenberg & Bland 2009: "Metallic DU is weakly radioactive and therefore contact with unbroken skin is an extremely low risk to health. However, when a DU round strikes an armoured target, it undergoes spontaneous partial combustion resulting in a fine aerosol of largely insoluble uranium oxides. Presence of this aerosol elevates the risk of potentially chemotoxic or radiotoxic exposure via inhalation or ingestion".
