摘　　要：为检验和提高浙江省辐射环境监测能力,确保监测数据和信息准确可靠,2022年9月在宁波市东钱湖开展全省环境γ辐射剂量率测量和宇宙射线响应比对,共有22家成员单位的37台仪器参与了5个监测点位的比对测量。其中,宇宙射线响应测试创新采用水面浮动码头平台,监测结果统一为γ辐射空气吸收剂量率,通过Z比分数方法进行评价。采用Z比分数得出仪器在5个监测点位均取得满意结果,从综合-Z值来看,37台仪器中有35台仪器测量结果为满意。高气压电离的稳定性和能量响应较好,塑料闪烁体的离散性较大,同类型的仪器响应值一致性较好。To test and improve the monitoring capacity of the radiation environment monitoring network in the province,and ensure the accuracy and reliability of monitoring data and information.In September 2022,a provincial cosmic ray response comparison and environmental Gamma Radiation dose rate measurement will be conducted in Dongqian Lake of Ningbo City,37 instruments of a total of 22 member units participated in the comparative measurement of 5 monitoring points,Innovative use of floating dock platform on water surface for cosmic ray monitoring points.The monitoring results are unified as Gamma Air absorption dose rate,Evaluated through Z-score method.Using Z-score,30 instruments achieved satisfactory results at 5 monitoring points.From the comprehensive Z-score,35 out of 37 instruments have satisfactory measurement results.The stability and energy response of high-pressure ionization are good,and the discreteness of plastic scintillators is relatively large.The response values of instruments of the same type are consistent.
