A Radiophotoluminescent glass rod dosimeter (GRD) system is applied to the dosimetry for broad energy range. When GRD is compared to a thermoluminescent dosimeter (TLD), GRD has the following characteristics: the first is the small variation among elements; the second is to be able to repeat reading; the third is the good repeatability of the read value. However, the energy response is not reported well for the low energy photon, and modified by encasing the element in the tin filter. To carry out the more accurate dosimetry for the low energy photon, the energy response for the monochromatic photon should be investigated. Therefore, we have obtained the more accurate energy response of GRI) for the monochromatic photon generated by the synchrotron radiation at Photon Factory (PF), High Energy Accelerator Research Organization. Furthermore, the energy response of GRD was evaluated with EGS4. As the result, the energy response steeply decreased in the region of less than 25keV. Moreover, the dispersion of the read value steeply increased in the region of less than 20keV. The causes of these results have been investigated by calculating the absorbed dose of GRD element using EGS4.
