本课题是从剂量学观点出发,对NaCl:Ca的热释光特性进行检查,并研究它在γ剂量学中应用的一个尝试。实验。NaCl:Ca(10~(-3))的多晶样品是用其水溶液结晶的方法得到的。样品先进行750℃、2小时退火,然后在室温的空气中冷却。在30℃～400℃的温度范围内对未经热处理和经过热处理的样品进行了热释光性能检查。样品的加热速度为180℃/分,并用单色光镜记录了不同温度的发射光谱,记录了发光曲线。实验使用的是~(60)Coγ源。结果:观察掺Ca和未掺Ca以及经过热处理和未
The topic from the dosimetry point of view, the thermoluminescence characteristics of NaCl: Ca examination, and its application in γ-dose of an attempt. experiment. The polycrystalline samples of NaCl: Ca (10 ~ (-3)) were obtained by crystallization from their aqueous solution. Samples were first annealed at 750 ° C for 2 hours and then cooled in air at room temperature. In the temperature range of 30 ℃ ~ 400 ℃ on the heat-treated and heat-treated samples were tested thermoluminescence performance. The sample was heated at a rate of 180 ° C / min and the emission spectra at different temperatures were recorded with a monochromatic light microscope and the luminescence curve recorded. The experiment used a ~ (60) Coy source. Results: The observation of Ca-doped and Ca-doped and heat-treated and not
