摘　　要：TLD用于个人剂量监测前必须进行刻度,从影响TLD剂量刻度准确性的相关因素出发,包括:刻度中使用的仪器原理、性能,退火、测量条件以及测量结果的曲线拟合方法等进行了较为系统的研究,建立了一套完整的TLD剂量刻度方法。结果表明:TLD刻度方法是切实可行的,能够保证个人剂量监测的准确性。The TLD （thermoluminescent dosimetry） must be calibrated before used in individual dosimetry. In this paper, some related issues that affect the accuracy of calibration, including principle and performance of the instruments, conditions of annealing and measuring, method of curve fitting are discussed and an appropriate calibration method is proposed. The results show that the method we proposed is valid and efficient, which ensures the accuracy of individual dosimetry.
