In a radiation individual monitoring program, the type testing of measuring devices is a great important part of the quality management system. The IEC-62387 standard applies to dosimetry systems that measure external photon and/or beta radiation within limited ranges of the associated physical parameters. In this work, a type-testing program was conducted for a manual thermoluminescence dosimetry (TLD) reader employing the IEC-62387 radiation and environmental performance criteria. The uncertainty of non-linearity of the response of the dosimetry system in a range of 0.7-850 mSv was obtained between -15% and + 17%, which fulfilled the IEC standard range of -16% to +18%. Furthermore, the total uncertainty of all reader tests was measured to be 12%, which was less than the criteria of 20% in the IEC standard. Thus, it can be concluded that the TLD reader met all requirements of the IEC standard for the reader-tests by an appropriate margin.

“…According to the IAEA requirements for dosimetry laboratories, a quality management system (QMS) is always required, ensuring the compliance with the standard criteria [1]. Some investigations, such as type testing programs, have been performed for various models of TLD readers by other researchers [2][3][4][5][6].…”

Abstract. A model of the 7200 hot gas automatic TLD card reader has been designed and manufactured in Iran. This study assesses some performance characteristics of the reader including the linearity of response, stability of readouts during a period of time as well as the reproducibility of TLD readouts. Furthermore, the coefficient of variations (COV) of the parameters has been studied and compared with those of standard criteria. The obtained results show that the TLD reader can be used efficiently in dosimetry laboratories.

The type testing of measuring devices is one of the most important parts of a quality management system in a personal dosimetry services program. In this study, based upon the International Electrotechnical Commission (IEC) 62387 criteria, a reader-testing program was performed for a home-made personal thermoluminescent dosimetry (TLD) reader. The stability of the reader, the effects of light exposure, temperature and fluctuations of primary power supply on TLD read-outs as the main parameters were investigated in this program. Moreover, this study assesses some important criteria of dosimetry system including the non-linearity of response, reusability, after effect and overload that may include significant contribution in the performance of a reader. The results showed that the TLD reader met all requirements of the IEC for the reader tests by a large margin.
