Monte Carlo simulation of the MTS-N (LiF:Mg,Ti) relative response in function of the photon energy

Abstract We performed MCNPX simulations and experimental measurements to determine the relative energy response of MTS-N detectors. The energy spectra simulated were monoenergetic beams (from 20 keV to 250 keV), X-rays beams (N and RQR), 137Cs and 60Co gamma radiation. Experimental measurements were made with groups of MTS-N detectors irradiated with standardized 137Cs gamma radiation beams and continuous X-ray beams (N and RQR quality). Relative intrinsic efficiencies were calculated combining the MCNPX simulations and experimental measurements. Our results showed a good agreement with other studies using LiF detectors and the same radiation qualities.
