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.

Apr. 25—Trace amounts of plutonium from decades of weapons work at Los Alamos National Laboratory have contaminated the Rio Grande at least as far as Cochiti Lake and could be in the regional ...
The Energy Department's Office of Environmental Management at Los Alamos said Thursday it was preparing a response to Ketterer's findings. Ketterer and Coghlan said the concerns now are the continued downstream migration of plutonium, absorption by plants and the creation of contaminated ash following wildfires.
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.
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 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. According to the U.S. Nuclear Regulatory Commission, the annual average dose per person from all natural and man-made sources is about 620 mrems.
Kersting is known for her work on the movement of plutonium and related compounds in the environment. In 1999 Kersting was the first to show that the movement of plutonium can occur on small particles, [4] research that was based on the presence of plutonium downstream from Nevada Test Site. [5] [6]
Apr. 14—It's been almost 80 years since the first atomic bomb was detonated, and scientists say there's still much to learn about how nuclear devices function as they reach the point of exploding.
