Scintillation radiation detectors are widely used in field of radiation measurement and applications for industrial and medical purposes due to their advantages of low manufacturing cost, high efficiency and applicability to many situations. The response function of radiation detectors is an important key to the understanding of radiation interactions occurring inside the detectors. The response functions for NaI(Tl), CsI(Tl) inorganic scintillation detectors were obtained through measurements and compared with deterministic computational simulation results. The simulation program provides detector response functions for incident photons with energies of 0 to 1.333 MeV, and the simulated results agreed well with the measurements for 137Cs, 60Co, 22Na and 133Ba source cases. The analyzed detector response function will contribute to better understanding of photon interactions in the detectors and to the development of new scintillation detectors.
