plutonium 239plutonium 240plutonium 241Values for the alpha half life of Pu/sup 239 ranging from 24,000 sintering time 240 years to 24,400 sintering time 100 years are reported. The isotopic content of the plutonium used for the half life determination was as follows: 99.92% Pu/sup 239/, ...
What is the half-life of plutonium? Plutonium: Plutonium is an artificial element created through scientific experimentation in a laboratory or as a byproduct of human activity. It does not occur in nature except in a few rare cases resulting from neutron capture by a uranium atom. There are...
