摘  要:核电产业是一个与国家安全息息相关、具有较强外部性和公益性的特殊产业,因而不同于一般的竞争性产业。为确保核与辐射环境安全,为核事业的安全、健康发展保驾护航,开展电离辐射环境监测是核事业发展和辐射环境保护的重要环节。石岛湾核电厂址辐射环境现场监督性监测系统(以下简称“监督性监测系统”)能实时在线连续监测核电厂周围辐射环境水平,半定量分析γ核素,辐射监测能力满足“国核安函[2014]49号”、《辐射环境检测技术》(HJ/T61-2001)的需求。该文对监督性监测系统中的外围辐射环境监测系统进行简单介绍。

Abstract: Nuclear power industry is a special industry closely related to national security, with strong externality and public welfare, so it is different from the general competitive industry. In order to ensure the safety of nuclear and radiation environment and to protect the safe and healthy development of nuclear industry, it is an important link to carry out ionizing radiation environmental monitoring for the development of nuclear industry and radiation environmental protection. The on-site supervisory monitoring system for radiation environment of Shidaowan Nuclear Power Plant site (hereinafter referred to as "supervisory monitoring system") can continuously monitor the radiation environment level around the nuclear power plant in real time and online, and semi quantitatively analyze the gamma nuclides. The radiation monitoring ability meets the requirements of "National Nuclear Safety letter [2014] No. 49" and radiation environment detection technology (HJ/t61-2001). This paper briefly introduces the peripheral radiation environment monitoring system in the supervisory monitoring system.

核能和核技术的应用日益广泛,核电不仅可以满足不断增长的电力需求,而且是改变中国能源结构、减少二氧化碳和二氧化硫排放的有效手段之一。然而任何技术的应用都是一把双刃剑,其在给人类带来好处的同时也会产生不利影响,核能和核技术的开发利用也不例外。电离辐射有其特殊性,看不见,摸不着,人体的感官无法感知,必须依靠专用的仪器设备,因此核电厂辐射环境现场监督性监测系统的建设是必不可少的环节。

外圍辐射环境监测系统是石岛湾核电监测系统的重要组成部分,由分布在石岛湾核电厂周围9个方向的12个监测子站构成(站点MS1~M12,分别为场区边界监测站、东钱家监测站、马兰耩监测站、宁津街道办监测站、东墩监测站、吕家庄监测站、核电厂施工生活区监测站、楮岛村监测站、东山街道办监测站、林家流监测站、耩后杨家监测站、前沿站监测站),用于辐射环境24 h连续自动监测。……
