文摘

A general overview of current investigative methods used in nuclear forensics and emergency responses is presented along with a range of new rapid methods. Borate fusion is presented as a valuable tool for rapidly dissolving complex samples with one key application being the elimination of matrix absorption effects that can compromise gamma ray spectrometry data. A novel, rapid liquid scintillation method is presented that uses multiple quench corrections to allow rapid screening and identification of alpha and beta contaminated water and other samples in emergency situations. A review of mass spectrometric methods shows their impact on rapid and precise isotopic analysis in the context of nuclear forensics and emergency situations.
