ISO 11483:2005 is an International Standard that provides three procedures for preparing plutonium sources and a method for measuring the activity ratio of 238Pu to (239Pu + 240Pu) using alpha spectrometry. It specifically focuses on the determination of 238Pu isotopic abundance in plutonium solutions, which is useful in conjunction with mass spectrometry for more accurate results.
