摘要
Abstract
[Objective]The comparability and substitution of three monitoring methods of environmental gamma radiation dose rate were discussed,the different application requirementsof the three methods were analyzed.[Methods]A total of 14 monitoring sites in Shenzhen were selected as the research objects,three monitoring methods of automatic continuous monitoring,cumulative dose monitoring and Immediate measurement were used to monitor environmental gamma radiation dose rate from July to December 2023 as the monitoring period,and the three methods were analyzed and verified by En value comparison.[Results]The monitoring results of the three methods were compared in pairs,The difference in comparison results between automatic continuous monitoring and cumulative dose monitoring is relatively minimal,The comparison results between automatic continuous monitoring and Immediate measurement show the greatest relative difference.[Conclusions]Automatic continuous monitoring and cumulative dose monitoring have better comparability and substitution.Due to the characteristics of its monitoring methods and instruments,Immediate measurement has limitations in the fixed-point monitoring of radiation environmental quality,and is more suitable for large-scale grid urban radiation environmental quality survey.关键词
