摘要
通过实验探讨了天然冰洲石热释光的若干基本特性.具体分析了天然冰洲石和经人工辐照冰洲石的热释光生长曲线、冰洲石的365℃热释光峰随升温速率的位移、冰洲石热释光峰对β辐射的热释光响应, 以及冰洲石的365℃热释光峰峰值温度随辐射剂量的不同而发生的变化.结果表明冰洲石具有良好的热释光特性,可作为热释光年龄测定的一种矿物.
Some fundamental characteristics of thermoluminescence (TL) of natural Iceland spar have been probed by experiments in this paper. It involves four aspects, including TL growth curves of natural Iceland spar, the change of peak temperature in different heating rates, TL response to βray irradiation and the 365℃ TL peaks with different βray irradiation doses.
