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.

全天候監(jiān)測輻射環(huán)境

中國建立國家、省、市三級輻射環(huán)境監(jiān)測體系，建成全國輻射環(huán)境質(zhì)量監(jiān)測、重點核設(shè)施周圍輻射環(huán)境監(jiān)督性監(jiān)測和核與輻射應(yīng)急監(jiān)測“三張網(wǎng)”，實現(xiàn)輻射環(huán)境全覆蓋全天候監(jiān)控。截至 2019年 6月，國家級輻射環(huán)境監(jiān)測網(wǎng)絡(luò)共有 1501個監(jiān)測點，包括 167個大氣輻射環(huán)境自動監(jiān)測站、 328個陸地點、 362個土壤點、 477個水體點、 48個海水點、 85個電磁輻射監(jiān)測點、 34個海洋生物監(jiān)測點，并建立 46套重點核設(shè)施周圍輻射環(huán)境監(jiān)督性監(jiān)測系統(tǒng)和食品放射性物質(zhì)監(jiān)測點。

中國輻射環(huán)境監(jiān)測數(shù)據(jù)顯示，全國范圍內(nèi)輻射環(huán)境質(zhì)量良好，處于天然環(huán)境輻射水平范圍內(nèi)，人工放射性核素活度濃度未見異常。位于核設(shè)施、核技術(shù)利用項目周邊的監(jiān)督性監(jiān)測數(shù)據(jù)顯示，全國核設(shè)施、核技術(shù)利用項目周圍環(huán)境輻射水平與建設(shè)前相比沒有明顯變化，公眾個人劑量遠低于國家限值，公眾健康和環(huán)境安全得到充分保障。
