In order to compare the dosimetric properties of two kinds of solid state detectors used for monitoring exteal 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 137 Cs and 60 Co γ-rays were used to irradiate the RPLGDs and TLDs,their dose linearky,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.
