Description
The evaluation of the source term in facilities related to the first stages of nuclear fuel involves the determination of radium concentration, as well as those from other radionuclide members of the uranium series. 226Ra activity can be determined by means of its 186 keV gamma-ray line. For this purpose it is necessary to estimate the interference due to 235U, also present in natural samples. This method has been applied successfully to several soil samples from an old uranium factory in Southern Spain. (author) 18 refs.; 3 figs.; 3 tabs
