Plutonium, like other actinides, readily forms a dioxide plutonyl core (PuO 2). In the environment, this plutonyl core readily complexes with carbonate as well as other oxygen moieties (OH −, NO 2 −, NO 3 −, and SO 4 2−) to form charged complexes which can be readily mobile with low affinities to soil.

In 1995, a report over 8,000 pages long was released by the Plutonium Working Group Report on Environmental, Safety and Health Vulnerabilities Associated with the Department's Plutonium Storage. This report listed Rocky Flats as having 5 of the 14 most vulnerable facilities based on plutonium environmental, safety, and health vulnerability at ...
After putting out the original source, there was an explosion in the ventilation system. The fire burned the filters that normally removed the plutonium from the building's air resulting in the release of 21 curies of plutonium into the atmosphere. [26]: 22, 23 For comparison the Fat Man, used 448 curies of plutonium for its core.

The environmental management field office pointed to a 2018 DOE study that estimated the radiation dose to a person who might recreate in the canyon is less than 0.1 millirem per year.
The plutonium separation process resulted in the release of radioactive isotopes into the air, which were carried by the wind throughout southeastern Washington and into parts of Idaho, Montana, Oregon, and British Columbia. Downwinders were exposed to radionuclides, particularly iodine-131, with the heaviest releases from 1945 to 1951.
The government says it will dispose of its 140 tonnes of radioactive plutonium - currently stored at a secure facility at Sellafield in Cumbria. The UK has the world's largest stockpile of the ...
In the past, one of the largest releases of plutonium into the environment has been nuclear bomb testing. Those tests in the air scattered some plutonium over the entire globe; this great dilution of the plutonium has resulted in the threat to each exposed person being very small as each person is only exposed to a very small amount.
