热释光剂量测量方法已经广泛用于辐射监测和防护的各个方面,成为个人和环境辐射剂量测量的一种重要手段。 热释光剂量仪测光系统中的光探测器是光电倍增管,其增益的影响因素很多,如高压、环境温度等,因此为了得到可靠的数据,提高测量准确度,仪器中通常装有校准光源,监测热释光灵敏度的变化。我们认为,理想的标准光源应该满足以下要求:1)亮度合适且光源长期稳定,2)光强温度系数小,3)对光电倍增管和工作人员来说是安全的,4)发射光谱与热释光探测器的光谱接近。
Thermoluminescence dose measurement methods have been used extensively in all aspects of radiation monitoring and protection as an important means of personal and environmental radiation dose measurement. Photoluminescence dosimetry metering system photodetector is a photomultiplier tube, the gain of many factors, such as high pressure, ambient temperature, etc. Therefore, in order to obtain reliable data, improve measurement accuracy, the instrument is usually equipped with a calibration Light source to monitor changes in thermoluminescence sensitivity. We believe that the ideal standard light source should meet the following requirements: 1) appropriate brightness and long-term light source stability, 2) low temperature coefficient of light intensity, 3) safe for photomultiplier tube and staff, 4) emission spectrum and heat The spectrum of the luminescence detector is close.
