No evidence of depleted uranium causing cancer, say scientific experts
Radiological exposure to depleted uranium does not result in a detectable effect on human health, reads the opinion of a group of independent scientific experts, received by the European Commission on 6 March. Although the possibility of a combined effect of exposure to toxic and carcinogenic chemicals and to radiation could not be excluded, the experts concluded that there is no evidence to support this hypothesis. 'I am grateful for the speedy work of the experts in producing this opinion. My Commission colleagues and I will take it into account when discussing the need for further action with regard to the health and environmental situation in the Balkans. I also look forward to seeing the results of work carried out by other bodies competent in this field,' said European Environment Commissioner Margot Wallström on receiving the report. Experts concluded that the calculated risk of getting leukaemia is far below the risk of solid cancers as the latency period is shorter. Exposure to depleted uranium through contamination of the environment or food chain was also considered. The group concluded that doses through, for example, ingestion of contaminated water or soil, or consumption of contaminated foodstuffs would be extremely low. In the scenarios at which the experts looked, exposure to depleted uranium would give a low dose, comparable to natural background levels. They therefore assert that there is no reason to believe that chemicals may change the magnitude of the potential radiation effects. The group of experts studied the characteristics, properties and uses of uranium and depleted uranium. They looked at direct pathways of exposure to humans as well as exposure due to contamination of the environment, the behaviour of uranium in the body and scientifically agreed predicted health effects per unit of exposure. The experts were requested to investigate the chemical toxicity of uranium, but the opinion relates only to the radiological health consequences. The group felt that they could not provide guidance for individuals who have been exposed to depleted uranium without knowing the specific exposure situation. They concluded that it would be more appropriate to monitor the environment rather than individuals. The group also considered themselves unqualified to provide guidance on the need for clean-up measures. Any intervention should take into account the specific situation in question, the opinion states. The group of experts was convened by the European Commission following concerns in a number of Member States following reports of cancer in soldiers who had served in the Kosovo region, where depleted uranium was used. Responsibility for dangers arising from ionising radiation is recognised in the Euratom Treaty as belonging to the Community
