北京市辐射环境自动监测系统研究

Study of the Automatic Monitoring System for Radiation Environment in Beijing City

辐射环境的自动监测是发展趋势,掌握辐射环境自动监测系统的应用是必不可少的。本文以北京市建设的辐射环境自动监测系统为背景,在介绍该系统的组成和工作原理的基础上,结合多年的运行维护经验,对质量保证措施、数据分析、运行情况以及在辐射环境监测中的作用进行了概述,并对引起γ剂量率变化的几种情况以及系统运行过程中出现的常见故障进行了分析,同时针对多发故障提出了日常运行维护中的注意事项和建议,对辐射环境自动监测系统的运行维护和数据分析可起到一定的借鉴作用。

With the development of the automatic monitoring for radiation environment,the application of the automatic monitoring system for radiation environment becomes more and more important.Taking the automatic monitoring system of radiation environment in Beijing City as an example,this paper introduces the composition and working principle of the system and summarizes the quality assurance methods,data analysis and operating conditions of the system in the monitoring of radiation environment based on the experience of operation and maintenance.The paper also analyzes some situations which cause the variations of γ dose rate and common faults in the operation process and,according to these faults,puts forward considerations and recommendations.The study has references for the operation maintenance and data analysis of the automatic monitoring system for radiation environment.
