摘要 用液体闪烁法测量放射性核素的方法已经应用很多年了。以液体闪烁法测量水中氚的放射性活度为例,分别对液体闪烁计数谱仪的主要性能参数:稳定性、本底计数率和探测效率进行讨论,建立了一套检定方法。 The method of radionuclide activity measurements by liquid scintillation counting is well established since many years. The example discussed the main performance of liquid scintillation spectrometry involved stability, background and efficiency, and established a check method.
