Abstract

Solid state dosimetry systems, including the early radiophotoluminescent (RPL) glass dosimeters, were investigated for application in environmental monitoring. RPL systems are under permanent development. The following dosimetric characteristics of the recently developed SC-1 flat RPL glass dosimeters with FGD-202 reader for environmental dosimetry were investigated: uniformity/batch homogeneity, reproducibility, linearity, detection threshold, energy dependence in air, on phantom and in water as well as the light sensitivity. All characteristics investigated fulfil the requirements of the IEC 61066:2006 Standard for personal and environmental dosimetry (IEC, 2006). It was found, that while the dosimeter is not sensitive for light because of automatic manipulation, the glass element itself could be used for 254 nm UV irradiation measurement. The UV light sensitivity differs for unirradiated and irradiated glass element. The authors recommend to extend the IEC Standard for personal and environmental monitoring also for RPL (and other) passive solid state dosimeters.
