摘要
本文提示效率示踪技术的测量误差随被测样品的化学或颜色淬灭程度的增加而增大,而且在强颜色淬灭情况下,呈现负误差。不同的闪烁液和体积对测量误差影响不大。效率示踪曲线的正确拟合很重要。
Measuring error involved in the efficiency tracing technique was shown to be increased with the chemical or colour quenching level of the tested sample and the error might become negative when the colour quenching was strong. The effects of different scintillation solutions and volumes on the error were found negligible. Appropriate methods for fitting the effici-ency tracing curve appeared very important.
