Actinides and Sr-89/90 in Vegetation: Fusion Method


U.S. DOE. "Actinides and Sr-89/90 in Vegetation: Fusion Method," SRS Manual L3.23, Procedure L3.23-10055. 2011


Analytical Method


This method describes procedures designed to analyze for Pu, Np, U, Th, Am/Cm isotopes in emergency or routine vegetation samples using alpha spectrometry. It provides rapid total dissolution of samples and efficient removal of alpha interferences prior to counting by alpha spectrometry. Strontium–89/90 is also separated and counted by gas proportional counting.
