Abstract
To obtain the impact of γ rays for the organic scintillation film detector (OSFD) in the field of pulsed fission neutron detection, the response of the OSFD to X or γ rays was studied with the Geant4 program. Combining with a semi-empirical scintillation efficiency function, the energy response function of the OSFD to γ rays was obtained. To verify the simulation result, the sensitivities of an OSFD employing 0.3 mm film to some discrete energy points were tested experimentally with 137Cs (662 keV) and 60Co (1.25 MeV) γ ray sources, as well as some discrete semi-monoeriergetic X ray points (48 to 208 keV) of a standard narrow band X ray device. The research is instructive for the improvement of the detector structure, and the results are valuable for the application of the detector in measuring pulsed X rays with wide energy distribution.关键词
