| 目的 探讨LabSOCS效率刻度方法在"涉核"事件应急监测实验室分析中的应用。 方法 用LabSOCS效率刻度方法模拟应急监测中采集的3种环境样品的探测效率,并与这3种样品的有源效率刻度的实测探测效率进行比较。结果 LabSOCS效率刻度方法模拟的探测效率(共20组比对值)与实测效率最大的相对偏差<15%,其中相对偏差小于5%的占70%。 结论 LabSOCS效率刻度方法可以代替实测标准刻度源得到效率的方法,满足"涉核"事件应急监测实验室快速分析的需求。 |

| Objective To explore the effectiviness of the method of LabSOCS(Laboratory sourceless calibration software) efficiency calibration in laboratory rapid analysis for emergency monitoring of nuclear incidents. Methods The detection efficiency of three kinds of environmental samples in emergency monitoring was calculated by using the LabSOCS efficiency calibration method, and compared with the values that were obtained by way of radioactive source calibration method. Results The maximum relative deviation of the detection efficiency between the two methods was less than 15%, and the values with relative deviation less than 5% accounted for 70%. Conclusions The LabSOCS efficiency calibration method might take the place of radioactive source efficiency calibration method, and meet the requirement of rapid analysis in emergency monitoring of the nuclear incidents. |
