Intercomparisons of new TLDs for environmental monitoring

Thermoluminescent dosimeters (TLDs) are an important element of monitoring networks. Intercomparisons and cross-calibrations can help to attain high international standards in the application of TLDs in routine environmental monitoring. This study focused on the performance of high sensitivity Al2O3:C and LiF:Mg, Cu, P TL detectors in comparison with widely used TLD systems based on TLD-700. The objectives of the study were to compare and improve laboratory calibrations, to compare the results of different dosimetry systems at the same field site, and to determine the field fading. The systems were compared through cross calibration and an exchange of dosimeters. Two measurement sites were selected in each country at which the environmental radiation field is expected to be different. The field doses at different locations, field fading under different climatic conditions, and the contribution of transit doses (because of air-mail) will contribute to the knowledge of the properties of the new ultrasensitive TLD materials Al2O3:C and LiF:Mg, Cu, P for application to environmental dosimetry.
