“…For use in complex workplace radiation fields such as at high-energy accelerators (19,20) , which are significantly different from calibration fields (Figure 3), a normalisation factor may be needed to compensate for deficiencies of detectors in terms of angle and energy dependence of response (21 -23) . Such normalisation factors can be obtained by field calibration in realistic radiation fields (24 -26) .…”

The accurate determination of personal dose equivalent requires the proper use of appropriate radiological quantities and units, knowledge of the dose equivalent response of the personal dosemeters used and detailed information on the fluence as well as dose equivalent spectra at the workplaces. This information can then be used to select the appropriate dosemeters, to set up the optimum calibration conditions and to introduce, in case of need, normalisation factors for application in specific radiation fields. High-energy neutrons contribute significantly to the radiation fields around high-energy particle accelerators. Examples for procedures and methods to determine personal dose equivalent at accelerator centres are given.

“…The RPLD is used by 7 %, OSLD by 3 %, fol lowed by direct ion stor age (DIS) do sim e ters, CR-39 and fis sion track de tec tors by 3 %, 2 % and 2 %, re spec tively [5]. The ba sic de mands for a TLD are good reproducibility, low hygroscopicity, and high sen si tivity for very low dose mea sure ments or good re sponse at high doses and in mixed ra di a tion fields [5,13,14].…”

Review of the thermoluminescent dosimetry method for the environmental dose monitoring

et al. 2021

Passive solid state dosimeters, such as thermoluminescence dosimeters, provide integrated measurement of the total dose and are widely used in environmental monitoring programs. The objective of this paper is to provide a comprehensive review on the use of thermoluminescent dosimetry methods for monitoring radiation dose in the environment. The article presents the part of the research results of the project PREPAREDNESS (EMPIR 2016 call for Metrology for Environment joint research 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 environ mental dosimetry methods are investigated. Differences in performing specific steps such as preheating, reading, annealing, minimizing fading, and others, are analyzed. The investigation was performed by means of qualitative literature review that showed the lack of information 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, control 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 understood in order to pro duce ac cu rate dose measurement results.
