Abstract Proportional counter is a gas detector widely used in the field of low energy photon measurement. In order to further study the radiation detection characteristics of proportional counter, Geant4 program was used to simulate the detection efficiency of low energy photon in the energy range of (2~90) keV. Proportional counter was used to measure the energy spectrum of standard radioactive sources129I, 152Eu and241Am, and the energy calibration curve and detection efficiency were obtained. The maximum deviation between the experimental measurement results and the simulation results is 2.29%, which is in good agreement, and verifies the accuracy of the simulation energy range (29.67~59.54)keV detection efficiency. The results show that the model of proportional counter established by Geant4 is consistent with the actual situation, which provides an important basis for the subsequent research on the radiation characteristics of proportional counter with Geant4.
