摘要
进行环境地表陆地γ辐射剂量率测量时,需要扣除仪器对宇宙射线的响应值。为了了解黔东南州辐射站监测设备对宇宙射线响应值的基本情况,本文使用6150AD-b和FH40G两台高灵敏度环境级γ剂量率仪对黔东南不同海拔高度、不同经纬度的水面进行宇宙射线电离成分所致空气吸收剂量率进行测量分析。结果表明,两台不同的设备在同海拔高度、同经纬度对宇宙射线的响应值不同,6150AD-b的响应值相对较高,而FH40G相对较低,同时经过理论计算得出了两台监测设备在黔东南州各县(市)的宇宙射线响应值,这为黔东南地区陆地γ辐射水平的计算提供了有力依据。
It is necessary to deduct the response value of the instrument to cosmic rays when measuring the radiation dose rate on the terrestrial surface.To understand the response of radiation monitoring equipment to cosmic rays in Qiandongnan Prefecture,in this paper,two high-sensitivity environmental-level gamma dose rate meters,6150AD-b and FH40G,are used to measure and analyze the air absorbed dose rate caused by cosmic-ray ionization components on the water surface at different altitudes,latitudes and longitudes in Qiandongnan.The results show that the responses of two different equipments to cosmic rays at the same altitude,the same latitude and longitude are different,response values from 6150AD-b are relatively high and from FH40G are relatively low.At the same time,the cosmic ray response values of the two monitoring devices in the counties(cities)of Qiandongnan Prefecture were obtained through theoretical calculations,which provides a basis for the calculation of terrestrial radiation in Qiandongnan.
