Plutonium, Pu, is a man-made metallic element. It is highly toxic, highly radioactive, pyrophoric, (spontaneously ignites on contact with air) and fissionable. It is extremely challenging to ...

Plutonium isotopes, particularly 239 Pu and 240 Pu, have become significant markers for understanding anthropogenic impacts on marine environments, especially following mid-twentieth century ...

The results of the study have provided unique information about the accumulation, distribution and sources of plutonium isotopes in glaciers. The concentration of 239+240 Pu activity turned out to ...
