Abstrakt

Accelerator mass spectrometry (AMS) represents a complementary technique for the detection of long-lived radionuclides through ultra-low isotope ratio measurements. In many cases, counting atoms rather than measuring decay products yields much higher sensitivities. For a few cases the powerful combination of activation and subsequent AMS detection is exemplified; typical radionuclides of interest have half-lives between some years and up to hundred million years. Lack of information exists for a list of nuclides for quantifying

production in fusion and fission environments as pointed out by nuclear data requests. A brief overview on detection limits at a typical AMS facility, the VERA facility, and some applications for selected long-lived radionuclides are given.
