Previously we characterized radiophotoluminescent (RPL) detectors for measuring both fast and thermal neutrons for personal monitoring. The linear response and angular dependence, which satisfies the ISO 21909 standard makes their application possible in neutron dosimetry. The polymer CR-39 track detectors remain one of the most used dosimeters where neutron radiations are to be measured, but the visualization process is time consuming. The difference between results obtained by RPL and CR-39 has been discussed mainly for fast neutrons. The present study has also looked at thermal neutron dosimetry, where we found few results in the literature for CR-39. Our measurements demonstrate that RPL detectors can be advantageously incorporated into a dosimeter to measure thermal neutrons.
此前，我们对用于个人监测的放射性光致发光（RPL）探测器进行了表征，该探测器可用于测量快中子和热中子。其线性响应和角度依赖性符合ISO 21909标准，这使得它们在中子剂量测定中得以应用。聚合物CR-39径迹探测器仍然是测量中子辐射时最常用的剂量计之一，但可视化过程耗时较长。RPL和CR-39所获结果之间的差异主要针对快中子进行了讨论。本研究还考察了热中子剂量测定，我们发现文献中关于CR-39在热中子剂量测定方面的结果很少。我们的测量表明，RPL探测器可有利地纳入剂量计中以测量热中子。
