摘　　要：在改进的手表红宝石事故剂量测读装置上，对不同种类、不同型号的手表红宝石热释光剂量学特性，尤其是照射后衰退性做了进一步研究．对其热释光发光曲线有了新的认识．通过优化测量参数，选取３６０℃测量，剔除低温峰，减缓了照射后衰退速率，提高了剂量测量的准确度，使手表红宝石作为辐射事故剂量计使用更为可靠．The characterization of thermoluminescence(TL) of different species and types of ruby was studied with a modified measuring instrument, especially for TL value decline of ruby after radiation.TL glow curves of ruby were further recognized. The measurement para neters were optimized. The decline rate of TL value of ruby was delayed after radiation and the accuracy of dose measurement of ruby as accident dosemeter increased by eliminating low temoerature peak and selecting 360℃ as a suitable measurement condition. The results make the use of ruby as radiation accident dosemeter more reliable.
