To study environmental samples, a 44.8% relative efficient well-type Ge detector with an active volume of 218 cm3 was calibrated in three different voluminous sample geometries. The models were tested by absolute full energy peak efficiency calibration with use of certified multinuclide standards. The efficiency results corrected for this experiment obtained self-absorption factors from the simple photon transmission experiments by using point-gamma sources for small cylindrical geometry and theoretically calculated self absorption factors based on the database related to mass attenuation coefficients for vial geometry. Tufa, soil, and marble were also measured at these counting geometries. The activity results obtained with these models were compared with each other.
