| Abstract: | A kind of efficiency function of HPGe y detector with respect to the point radioactive sources and the method of determining its parameters are brought forward. By means of the function and numerical method, ^226Ra, ^232Th and ^40K in two standard samples are analyzed, and the results are coincident with the known parameters, so the applicability of the function and the method is proved. In principle, this nondestructive analytical method can be applied to samples with any shapes. |
