The Plutonium-238 used in RTGs has a half-life of 88 years, as opposed to the plutonium-239 used in nuclear weapons and reactors, which has a half-life of 24,100 years. [ full citation needed ] In April 1964 a SNAP-9A failed to achieve orbit and disintegrated, dispersing roughly 1 kilogram (2.2 lb) of plutonium-238 over all continents.
Trace amounts of plutonium-238, plutonium-239, plutonium-240, and plutonium-244 can be found in nature. Small traces of plutonium-239, a few parts per trillion , and its decay products are naturally found in some concentrated ores of uranium, [ 54 ] such as the natural nuclear fission reactor in Oklo , Gabon .

The New Mexico Administrative Code sets an unenforceable guideline of 1.5 picocuries of plutonium per liter of water in the Rio Grande, and water samples from the early 2010s near the Buckman ...
Plutopia: Nuclear Families, Atomic Cities, and the Great Soviet and American Plutonium Disasters is a 2013 book by American environmental historian Kate Brown.The book is a comparative history of the cities of Richland, in the northwest United States adjacent to the U.S. Department of Energy Hanford Site plutonium production area, and Ozersk, in Russia's southern Ural mountain region.

Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...
Tell the whole story of plutonium’s use. Our entire region should be extremely proud of the B Reactor. A massive edifice, built in a year, under tight security.
The odd numbered fissile plutonium isotopes present in spent nuclear fuel, such as Pu-239, decrease significantly as a percentage of the total composition of all plutonium isotopes (which was 1.11% in the first example above) as higher and higher burnups take place, while the even numbered non-fissile plutonium isotopes (e.g. Pu-238, Pu-240 and ...
The B Reactor was the world's first full-scale plutonium production reactor. Instead of being cocooned, it was turned into a National Historic Landmark in 2008.
