Americium was identified by Seaborg, James, Morgan and Ghiroso in the later half of 1944. Can be prepared in pure form by extraction as a decay product from neutron bombarded plutonium.  Must handled with great care because of the contamination to the person handling of Americium.  It is used as a portable source for gamma radiography.
