Comparisons of dosimetric properties between GD-300 series of radiophotoluminescent glass detectors and GR-200 series of thermoluminescent detectors

Abstract

In order to compare the dosimetric properties of two kinds of solid state detectors used for monitoring external exposures, experiments were performed for the GD-300 series of radiophotoluminescent glass detectors (RPLGD) and the GR-200 series of thermoluminescent detectors (TLD). X-rays and 137Cs and 60Co γ-rays were used to irradiate the RPLGDs and TLDs, their dose linearity, uniformity/reproducibility of signal, fading effect and energy dependence were compared. Both kinds of the detectors have generally good dosimetric properties. The dose linearity and energy dependence of the GD-351 dosimeters and the TLDs are nearly the same, but the RPLGD is much better than the TLD in terms of the uniformity and fading effect.
