ＧＲ２００Ａ（本实验室产品）与ＭＣＰＮ（波兰产品）均为ＬｉＦ（Ｍｇ，Ｃｕ，Ｐ）片状探测器，现将ＧＲ２００Ａ和ＭＣＰＮ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ＭＣＰＮ的１６倍；６次重复使用的结果ＧＲ２００Ａ灵敏度无变化，ＭＣＰＮ灵敏度下降了２６％；抗潮湿性能ＧＲ２００Ａ更优于ＭＣＰＮ。在９８％的相对湿度下贮存２５ｄ后，ＧＲ２００Ａ灵敏度和颜色均无明显变化，而ＭＣＰＮ由原来的白色转变为淡棕色。实验结果表明：ＧＲ２００Ａ剂量学特性超过了ＭＣＰＮ。 GR  200A (the laboratory product) and MCP  N (Polish products) are LiF (Mg, Cu, P) chip detectors, now GR  200A and MCP  N in the luminous curve, sensitivity, The sensitivity of GR-200A was 16 times that of MCPN; the results of 6 times repeated use showed no change in the sensitivity of GR200A; the content of MCPN Sensitivity decreased by 2  6%; Moisture resistance GR  200A better than MCP  N. After stored at 98% relative humidity for 25 days, there was no significant change in the sensitivity and color of GR-200A, while MCP-N changed from the original white to light brown. The experimental results show that: GR  200A dosimetric characteristics than MCP  N.
