Abstract

Abstract: A method is applied to build a virtual simulation radiometric measurement system. The mathematical and physical models of gamma ray interaction with matter, radiation sources, measurement electronics system and protective materials are constructed by using Monte Carlo method. Through numerical calculation and scene simulation of the radiation measurement system, virtual simulation acquisition and energy spectrum processing of radiation measurement data are realized. It, the system, can simulate single channel measurement and computer multi-channel measurement experiments. It can realize energy measurement, activity measurement and energy spectrum measurement of mixed, unknown or custom radiation sources in different size crystals. It can be used for specific lead activity and Half-value Layer measurement, protection performance measurement and evaluation of different materials, development and test calibration of radiometric instruments, comparison of energy spectra of unknown radiation sources, etc.

Key words: radiometric measurement, simulation system, monte carlo, energy spectrum
