摘要/Abstract

摘要： 2012年9月8日至10月7日,在三门核电站周围地区实施了环境辐射本底航空测量调查,完成航空测量面积7 192.7 km²,采集了99 577组航空测量数据,给出了三门核电站周围地区环境辐射本底水平、天然放射性核素⁴⁰K、²³⁸U、²³²Th活度浓度的分布。结果表明:三门核电站周围地区环境辐射水平显现为“西北地区高、西南与东北地区偏高、中部地区中低水平”的特点。未发现有可分辨的人工放射性核素分布,亦未发现失控的放射源,发现了2个航测辐射热点,均为地质环境中天然放射性核素偏高引起。

Abstract: During September 8th to October 7th in 2012,an airborne gamma-ray spectrometric survey was implemented to investigate the environmental radiation background around the Sanmen NPP. This survey covered an area of 7 192 km²and collected 99 577 sets of data, with which the environmental radiation background measurements and activity concentrations of natural Potassium-40, Uranium-238 and Thorium-232 around Sanmen NPP were calculated. It is the conclusion that the dose rate of northwest area around Sanmen NPP is high, southwest and northeast is relative high, and the central area is low. No resoluble manmade radionuclide or any lost radioactive sources was identified. Two airborne radiation hot-point’s were identified, which are aroused by higher natural radiation in geological environment.

Key words: airborne gamma-ray spectrometric survey, the area around Sanmen NPP, environmental radiation background, quality assurance
