| The TR5500 Thermoluminescent Dosimeter (TLD) reader was specifically designed and developed for the automated and efficient readout of Thermoluminescent (TL) chips and pellets in Iran. In accordance with International Atomic Energy Agency (IAEA) requirements for dosimetry laboratories, implementing a comprehensive Quality Management System (QMS) is essential to ensure adherence to standard criteria. This study aimed to evaluate key characteristics of the reader, including response non-linearity, Coefficients of Variation (COV), readout stability over time, and the reproducibility of TLD measurements. LiF: Mg, Cu, P TLDs were exposed to a standard photon radiation field and subsequently read using the TR5500 reader. The characteristics were then calculated and compared against the relevant criteria outlined in International Electrotechnical Commission (IEC) and American Society for Testing and Materials (ASTM) standards, such as ASTM E668-10 and IEC 62387. The reader met the key international standard requirements and, in certain aspects, even surpassed them. The device exhibited excellent stability and reproducibility in readouts, confirming its robust reliability and long-term suitability for routine use in various accredited dosimetry laboratories. | ||
