Levels of trace radiopurity in active detector materials is a subject of major concern in low-background experiments. Among the radio-isotopes, 40 K is one of the most abundant and yet whose signatures are difficult to reject. Procedures were devised to measure trace potassium concentrations in the inorganic salt CsI as well as in organic liquid(More)
Levels of trace radiopurity in active detector materials is a subject of major concern in low-background experiments. Procedures were devised to measure trace concentrations of ı129 in the inorganic salt CsI as well as in organic liquid scintil-lator with Accelerator Mass Spectrometry (AMS) which leads to improvement in sensitivities by several orders of(More)
