Plutonium and health

TOXICOLOGICAL PROFILE FOR PLUTONIUM , Agency for Toxic Substances and Disease Registry Division of Toxicology and Environmental Medicine/Applied Toxicology Branch,  Atlanta, Georgia

” …….Plutonium may remain in the lungs or move to the bones, liver, or other body organs. It generally stays in the body for decades and continues to expose the surrounding tissues to radiation. Lung, liver, and bone cancer You may develop cancer depending on how much plutonium is in your body and for how long it remains in your body. The types of cancers you would most likely develop are cancers of the lung, bones, and liver…….

The risks of mortality and morbidity from bone and liver cancers have also been studied in Mayak workers. Increasing estimated plutonium body burden was associated with increasing liver cancer mortality, with higher risk in females compared to males…….

Cardiovascular Effects. Epidemiological Studies in Humans. Possible associations between exposure to plutonium and cardiovascular disease have been examined in studies of workers at production and/or processing facilities in the United Kingdom (Sellafield)……..  within a cohort of Sellafield workers   morality rate ratios for plutonium workers were significantly elevated for deaths from circulatory disease and ischemic heart disease . ….

the Mayak studies provide evidence for increased risk of cancer mortality (bone, liver, lung) in association with increased internal plutonium-derived radiation dose and/or body burden, with approximately 4-fold higher risks in females compared to males…….

Risks of mortality and morbidity from bone and liver cancers have also been studied in Mayak workers ….. Increasing estimated plutonium body burden was associated with increasing cancer mortality, with higher risk in females compared to males…..

U.K. Atomic Energy Authority and Atomic Weapons Establishment Workers. ………..The mortality rate ratio was significantly elevated for breast cancer  and cerebrovascular disease  in a cohort of female Sellafield workers identified as plutonium workers……..

Comparisons of mortality rates between plutonium workers and other radiation workers yielded significantly elevated mortality rate ratios for all deaths , all cancers , breast cancer, circulatory disease , and ischemic heart disease.

GENOTOXICITY Abundant information is available regarding the genotoxicity of ionizing radiation……….Although epidemiological studies do not provide conclusive evidence that plutonium produces genetic damage in humans, results of some studies provide suggestive evidence of dose-related increases in chromosomal aberrations in plutonium workers with measurable internalized plutonium……. ……https://www.atsdr.cdc.gov/toxprofiles/tp143.pdf?fbclid=IwAR1iffNMF8xj33aBhDW-zhtFzPejF0eNlQ5QUaIgxBhCcujUKU0XRC8NvMc
