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.

Following the 2011 Fukushima I nuclear accidents, there has been increased focus on the risks associated with seismic activity and the potential for environmental radioactive release. Genpatsu-shinsai, meaning nuclear power plant earthquake disaster, is a term coined by Japanese seismologist Professor Katsuhiko Ishibashi in 1997. [140]
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 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.
The actinide series is a group of chemical elements with atomic numbers ranging from 89 to 102, [note 1] including notable elements such as uranium and plutonium.The nuclides (or isotopes) thorium-232, uranium-235, and uranium-238 occur primordially, while trace quantities of actinium, protactinium, neptunium, and plutonium exist as a result of radioactive decay and (in the case of neptunium ...

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.
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]
