摘要

在《水质 总α放射性的测定 厚源法》(HJ898-2017)、《水质 总β放射性的测定 厚源法》(HJ899-2017)中,串道比计算公式有多余项.本文通过理论推导和实验方法进行了验证.结果表明,根据该串道比计算公式给出的结果有更大的偏差估计.

Abstract

In the"Water Quality-Determination of Gross Alpha Activity-Thick Source Method"(HJ898-2017),"Water Quality-Determination of Gross Beta Activity-Thick Source Method"(HJ899-2017),there are multiple terms in the formula for calculating the cross-talk correction factor.This article has been validated through theoretical derivation and experimental methods.The results indicate that there is a greater estimation of bias based on the formula for calculating the cross-talk correction factor.
