A procedure for synthesis of the highly sensitive pellet-type LiF:Mg,Cu,Na,Si thermoluminescent (TL) detector has been newly developed. It was found that the optimum concentrations of dopants for a pellet-type LiF:Mg,Cu,Na,Si TL detector were found to be Mg: 0.2 mol %, Cu: 0.05 mol %, Na: 0.9 mol%, and Si: 0.9 mol%. The TL sensitivity of this new detector was about 30 times higher than that of the TLD-100 by light integration measurements. Reusability study of the detector was carried out for 10 cycles. The results show that the coefficients of variation for each detector separately did not exceed 0.016, and that for all 10 detectors collectively was 0.0054.
一种用于合成高灵敏度颗粒型LiF:Mg,Cu,Na,Si热释光（TL）探测器的方法已被新开发出来。结果发现，颗粒型LiF:Mg,Cu,Na,Si TL探测器的最佳掺杂剂浓度为Mg: 0.2 mol%，Cu: 0.05 mol%，Na: 0.9 mol%，Si: 0.9 mol%。通过光积分测量，这种新型探测器的TL灵敏度比TLD - 100高约30倍。对该探测器进行了10个循环的可重复使用性研究。结果表明，每个探测器单独的变异系数不超过0.016，10个探测器总体的变异系数为0.0054。
