Modern method for determining the specific activity of natural radionuclides

Abstract

The purpose of this work is to get acquainted with the basic properties and laws of interaction with the substance of gamma radiation. The practical part of the work includes an acquaintance with the technique and technique of gamma-ray spectroscopy by the example of recording the gamma spectrum of a Cs137 preparation with a spectrometer with a scintillation detector, followed by calibration of the energy scale. After that, on a calibrated spectrometer, it is proposed to determine the attenuation coefficient and estimate the energy of gamma quanta.
