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 (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 16 times that of MCPN; the results of 6 times repeated use showed no change in the sensitivity of GR200A; the content of MCPN 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.
