摘要
ＧＲ２００Ａ（本实验室产品）与ＭＣＰＮ（波兰产品）均为ＬｉＦ（Ｍｇ，Ｃｕ，Ｐ）片状探测器，现将ＧＲ２００Ａ和ＭＣＰＮ在发光曲线、灵敏度、重复使用、抗潮湿性能、本底、探测阈、光敏等性能进行平行对比实验，其中ＧＲ－２００Ａ的灵敏度为ＭＣＰＮ的１６倍；６次重复使用的结果ＧＲ２００Ａ灵敏度无变化，ＭＣＰＮ灵敏度下降了２６％；抗潮湿性能ＧＲ２００Ａ更优于ＭＣＰＮ。在９８％的相对湿度下贮存２５ｄ后，ＧＲ２００Ａ灵敏度和颜色均无明显变化，而ＭＣＰＮ由原来的白色转变为淡棕色。实验结果表明：ＧＲ２００Ａ剂量学特性超过了ＭＣＰＮ。
GR 200A and MCP N are the same kind of LiF(Mg, Cu, P) chip detectors. The main dosimetric characteristics of two LiF (Mg, Cu, P) chip TLDs (GR 200A made in Solid Dosimetric Detector & Method Laboratory, Beijing, and MCP N made in Poland) are compared, including glow curve structure, TL sensitivity, anti moisture, reproducibility, background, detection threshold and photosensitivity. Sensitivity of GR 200a is 1 6 times as much as that of MCP N. The sensitivity of GR 200A is stable after being used for six times, but the sensitivity of MCP N dropped 2 8%, and its colour turned from white into light brown. The sensitivity and colour of GR 200A didnt vary after being stored for 25 days at 98% RH, by comparison the sensitivity of MCP N dropped 14%, and its colour turned into light brown. It was found that the GR 200A TLD is for superior to the MCP N TLD in above mentioned characteristics.
