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.
