Abstract
Comparative measurements are presented on standard ray volume sources used for the assay of natural radioactivity. The sources compared were made from Canadian and Russian uranium and thorium reference ores as well as from standardized solutions of Ra-226 and Th-238. Tn addition, for Th-232 chemically pure thorium compounds were used. Measurements were carried out with three types of detector, hyperpure Ge, Ge(Li) an d NaI(Tl). The results of many comparative measurements in two differe nt laboratories are discussed.
