摘要
为掌握新引进的辐射光致发光玻璃剂量计的辐射剂量学特性,通过用次级标准剂量学实验室的X射线照射装置、60Coγ放射源(1250 keV)及经检定的137Csγ放射源(662 keV)照射,考察了GD-300系列辐射光致发光玻璃剂量计的剂量线性、均匀性、重复性、衰退特性和能量响应等剂量学性能。实验研究结果表明,GD-300系列辐射光致发光玻璃剂量计的辐射剂量学性能良好,适合作为放射工作人员外照射剂量、放射诊疗受检者与患者剂量的测量,也适用于环境辐射的长期累积测量。
In order to grasp the dosimetric toluminescent glass dosimeter (RPLGD), properties of the newly imported radiophoexperiments for studying the dose linearity, uniformity and reproducibility of signal, fading effect and energy dependence of the RPLGD were performed by using the X-ray emitting device and 60Co as well as 137Cs sources in a secondly standard dosimetry laboratory. The general dosimetric properties of the RPLGD are fairly good. It indicates that the RPLGD is suitable for monitoring the external exposure of radiation workers, evaluating the patient dose from medical exposure, and monitoring the long-term integrated environmental radiation levels.
