全天候监测辐射环境
中国建立国家、省、市三级辐射环境监测体系，建成全国辐射环境质量监测、重点核设施周围辐射环境监督性监测和核与辐射应急监测“三张网”，实现辐射环境全覆盖全天候监控。截至 2019年 6月，国家级辐射环境监测网络共有 1501个监测点，包括 167个大气辐射环境自动监测站、 328个陆地点、 362个土壤点、 477个水体点、 48个海水点、 85个电磁辐射监测点、 34个海洋生物监测点，并建立 46套重点核设施周围辐射环境监督性监测系统和食品放射性物质监测点。
中国辐射环境监测数据显示，全国范围内辐射环境质量良好，处于天然环境辐射水平范围内，人工放射性核素活度浓度未见异常。位于核设施、核技术利用项目周边的监督性监测数据显示，全国核设施、核技术利用项目周围环境辐射水平与建设前相比没有明显变化，公众个人剂量远低于国家限值，公众健康和环境安全得到充分保障。
Round-the-clock Radiation Environment Monitoring
A three-tiered radiation environment monitoring system is in place at national, provincial and municipal levels together with networks for national radiation environment monitoring, focused surveillance and monitoring of the radiation environment in the vicinity of key nuclear facilities, and nuclear and radiation emergency monitoring, providing round-the-clock radiation monitoring in all areas. As of June 2019, the national radiation environment monitoring network had 1,501 monitoring sites, including 167 automatic monitoring sites for atmospheric radiation, 328 land sites, 362 soil sites, 477 inland water sites, 48 seawater sites, 85 electromagnetic radiation sites and 34 marine life sites. There were also 46 focused radiation environment surveillance and monitoring mechanisms in the vicinity of key nuclear facilities, in addition to sites for monitoring radioactivity in food.
Data from radiation environment monitoring show that radiation levels in the environment across the country are within the acceptable range of natural environmental radiation, and that the activity concentration levels of artificial radionuclides are also within their normal range. Surveillance and monitoring data show that radiation in the environment around national nuclear facilities and nuclear technology utilization projects has not changed significantly compared with the levels of radiation prior to the construction of these facilities and projects, and the radiation dose for individual members of the public remains far below the national limit. No real threats to public health and environmental safety have been identified.
