Pulsed optically stimulated luminescence (POSL) measurement system was developed in this research. The system was used in the performance test. Moreover, the method was applied to dose recovery test using a known dosed soil.From the results, the POSL dosimetry could be developed with higher detection limit than the expected value. The method needed the simple pretreatment procedure because the sample had relatively small amout of quartz. However, The dosimetry could shorten the pretreatment time from 3 days to some hours.

在这项研究中开发了脉冲的光学刺激发光（POSL）测量系统。该系统用于性能测试。此外，该方法使用已知的剂量土壤应用于剂量恢复测试。从结果，可以开发POSL剂量测定法，检测极限高于预期值。该方法需要简单的预处理程序，因为样品的Quartz相对较小。但是，剂量测定可能会使预处理时间从3天缩短到几个小时。
