Passive solid state dosimeters in environmental monitoring

Thermoluminescence (TL) and radiophotoluminescence (RPL) passive solid state dosimeters are important elements of environmental monitoring networks. Environmental dosimetry systems have to fulfil the requirement to measure the man-made contribution to environmental radiation (1:10) under variable environmental conditions (UV sunlight, humidity, temperature). Performance testing and procedural specifications may be found in national and international standards. Some important dosimetric characteristics of the recently developed SC-1 flat RPL glass dosimeters with FGD-202 reader for environmental dosimetry were compared to various high sensitivity TL dosimeters. All characteristics of RPL and TL dosimeters investigated fulfil the requirements of the new IEC 61066:2006 Standard for personal and environmental dosimetry. To reach international standards and to improve the environmental dosimetry method there is a need for intercomparisons. The protocol and the aim of the intercomparison are discussed.
