Objective To evaluate the reliability of a thermoluminescence dosimetry system by testing the key performance indexes. Methods Under the criteria of JJG593-2006, GBZ207-2016, and GB/T10264-2014, eight indexes of the thermoluminescence dosimetry system were examined, including the batch homogeneity, stability, angle response, linearity, energy response, quantity inspection, residual dose, and the minimal detection limit. Moreover, the results were compared with the related standards. Results The results of various performance indexes met the criteria of the national and industrial standards. Conclusion The thermoluminescence dosimetry system meets the technical requirements of relevant standards, and can be used for personal and environmental dose monitoring.
