摘要/Abstract

摘要： 2013年12月,环境保护部辐射环境监测技术中心在四川省凉山彝族自治州组织了全国辐射监测网络的环境γ辐射剂量率和宇宙射线响应测量比对。共有32家成员单位的47台仪器设备参与了7个环境测点的比对测量,比对结果统一到γ空气吸收剂量率,采用Z比分数值分别对不同型号仪器的测量结果进行评价。比对结果显示,闪烁计数器测量数据的离散性较高压电离室大。除宇宙射线响应测点外,两类仪器的测量结果保持着较好的线性。

Abstract: In December 2013, an intercomparison of environmental gamma radiation dose rate and cosmic ray response measurements within the national radiation environmental monitoring network was held in Liangshan Yi Autonomous Prefecture, Sichuan Province, which was organized by RadiationMonitoring Technical Center of Ministry of Environment Protection. A total of 47 sets of instruments from 32 member units participated in the intercomparison measurements at 7 environmental measuring points. All the results are unified interms of absorbed dose rate in air. Results of different types of instruments are independently evaluated by Z score values. It is found that the data of scintillation counters have relatively wider dispersion than those of high pressure ionization chambers. Besides the cosmic ray response points, the results of both keep good linearity.

Key words: γ dose rate, Dose ratemeter, Intercomparison, Calibration
