REVIEW OF THE THERMOLUMINESCENT DOSIMETRY METHOD FOR THE ENVIRONMENTAL DOSE MONITORING

Passive solid state dosimeters, such as thermoluminescence dosimeters, provide integrated measurement of the to tal dose and are widely used in en viron men tal monitoring pro grams. The objective of this paper is to pro vide a comprehensive re view on the use of thermoluminescent dosimetry methods for monitoring radiation dose in the environment. The article presents the part of the re search results of the project PREPAREDNESS (EMPIR 2016 call for Metrology for Environment joint re search project) with a particular objective to harmonize procedures used by dosimetry services, relevant authorities and Institutes across the Europe. To achieve this, different monitoring routines that are based on passive environmental dosimetry methods are investigated. Differences in performing specific steps such as preheating, reading, annealing, minimizing fading, and others, are an alyzed. The investigation was per formed by means of qualitative literaturere view that showed the lack of in formation about specific steps. The conclusion of this work is that thermoluminescent dosimetry measurement system has to be type-tested even though the testing procedure is complicated. In addition to this, con trol dosimeters should be introduced, International Organization for Standardization protocols should be followed during calibration, and finally, parameters influencing the measurement uncertainty have to be identified and well under stood in order to produce accurate dose measurement results.
