Popis:	In this work the efficiency calibration curves for a HPGe gamma detector were obtained from soil standards prepared in our laboratory using typical Argentine regional soils. They were made in pot and Petri dish geometries, for different soil granulometries, by using two mixed nuclide reference solutions manufactured by Eckert & Ziegler and provided by the IAEA. The efficiency curves obtained were tested with the reference materials IAEA-375, IAEA-447, CNEA-81-11 as well as the soil sample used in the IAEA-2013 proficiency test. The results allow to improve the quality in the analytical measurements on the content of radionuclides in local soils.
