К расчету спектрального распределения гамма-излучения над полубесконечным источником

Abstract

Express-analysis of the radionuclide content in soil on large territories is performed with the use of gamma-spectrometry method above the soil surface. The relations between the registrated spectra and the radioactive contamination level, it’s in-depth profile are of great importance to work out apropriate apparatus. In this paper the above relations have been investigated by Monte-Carlo simulation. The developed program tools can be used when determing the dependence of the spectrum form and the character of radionuclide vertical distribution.
