The chemical element plutonium is classed as an actinide metal. It was discovered in 1940 by Glenn Seaborg, Edwin McMillan, Joseph Kennedy, and Arthur Wahl. Data Zone Classification:Plutonium is an actinide metal Color:silvery-white Atomic weight:(244), no stable isotopes ...
Obtaining Pu background data in the environment is essential for contamination source identification and assessment of environmental impact of Pu released from the Fukushima Daiichi nuclear power plant (FDNPP) accident. However, no baseline information on Pu isotopes in Fukushima Prefecture has been repo...

Plutonium 238 is created by uranium 238 capturing a deuterium atom, to become neptunium 238, and then a beta decay to become plutonium 238. If you remember back to my episode on uranium, the two common isotopes of uranium, 235 and 238, behaved differently in nuclear reactions. In particula...
environmental concerns can thus be beyond a regional scale because of this transport. For example, Pu isotopes of sediment and seawater in the China Sea suggested such transport from close-in fallout from the Pacific Proving Grounds in the Marshall Islands where a large-scale USA nuclear testing ...
