自然光激发荧光粉的主要成份为氧化稀土 ,往往伴生一定量的天然放射性物质。其作为一种特殊样品 ,在进行总 β放射性测量时如选用测量装置或方法不当 ,测量结果将有可能产生几个数量级的失误。本文针对国内实验室常见的几种类型探测器装置 ,对荧光粉样品总 β放射性测定方法及?
Natural light-excited phosphor is the main component of rare earth oxides, often associated with a certain amount of natural radioactive material. As a special sample, if the measurement device or method is not suitable for measuring the total beta radioactivity, the measurement result may be several orders of magnitude error. In this paper, several types of detector devices commonly used in domestic laboratories, the determination of total beta radioactivity of phosphor samples and?
