摘　　要：用配备通用自动计数与数据处理装置的井型NaI(Tl)探测器对^(125)I活度进行了绝对测量。用DD8000多道分析器和3路计数器的测量验证了它的可靠性。研究了峰交叉对测量结果的影响,并给出各项不确定度分量的计算公式。The paper describes absolute measurement of ^(123)I activity by well-type Nal (T1) detector equipped with common auto-counting and data processing device. The experiment reliability is verified by the measurement of DD8000 type multichannel analyser and 3-routes counter. The peak overlap effect on measured results is studied and the calculating formulas of uncertainty are given.
