Abstract
Resonance Ionization Mass Spectrometry (RIMS) has nowadays reached the stat us of a routine method for sensitive and selective ultratrace determination of long-lived radioactive isotopes in environmental, biomedical and techni cal samples. It provides high isobaric suppression, high to ultra-high isot opic selectivity and good overall efficiency. Experimental detection limits are as low as 10(6) atoms per sample and permit the fast and sensitive det ermination of ultratrace amounts of radiotoxic contaminations. Experimental arrangements for the detection of different radiotoxic isotopes, e.g. Pu23 6-244, Sr-89,Sr-90 and Tc-99 in environmental samples are described, and th e application of RIMS to the ultrarare long-lived radioisotope Ca-41 for co smochemical, radiodating and medical purposes are presented.
