Abstract

A procedure of the airborne gamma spectrometer data interpretation is suggested. The Monte-Carlo simulations using the EGS-4 code were carried out to obtain the theoretical gamma spectra for different radioactive isotopes distributions. Then the spectrum intervals associated with the direct and scattered gamma-radiation of experimental and theoretical spectra are compared and concentration of natural (U, Th, K, etc.) and artificial (¹³⁷Cs, ¹³⁴Cs, etc.) isotopes as well as the parameters of their distribution in soil for defined a priori models are determined
