Simulation Using Geant 4 of Axas-D System With Registration K-Series of Iodine in Activated Carbon for Ventilation Systems NPP

Abstract

The material shows the results of using the Geant4 program to simulate the operation and capabilities of the SKIF stand when recording radiation K-series with detector the AXAS-D of stable iodine in activated carbon, which is used for air purification at the NPP. The radiation spectra obtained in different situations are shown: at the entrance and exit of the measuring installation; and their processing. The parameters of the registration system were obtained – efficiency and dependence on the thickness of the detector crystal.
