Abstract
The calibration procedure of the gamma spectrometer UDS-HZ-BGO, created at the IPGG SB RAS, is formulated. The efficiency of the technique has been confirmed experimentally. Using the example of gamma-spectrometric studies of the territory of the IPGG SB RAS, the presence of a temperature drift of the device response caused by insufficient temperature compensation was recorded. The dependences of the change in the value of the measured content of radioactive elements U, Th, K at points on the territory of the IPGG on the ambient temperature in the range from plus 15 C to minus 20 C are obtained. The results are recommended to be used for temperature correction of element concentrations during radiometric survey.
