通过在海阳核电站周围地区环境辐射本底的航空测量调查,查明了海阳核电站周围地区环境辐射本底水平,天然放射性核素40K、238U(226Ra)、232 Th活度浓度的分布;环境辐射水平显现“中部及西北与东北局部地区偏高、西南与北部地区中低水平”的特点.137 Cs和60Co面活度均低于探测限,未发现有可分辨的其它人工放射性核素分布,亦未发现失控的放射源,发现了2个航测辐射偏高点(区),均为地质环境中天然放射性核素偏高引起.
Airborne Gamma-ray Spectrometric Survey of Environmental Radiation Background Around Haiyang NPP, Shandong
Airborne gamma-ray spectrometric survey of environmental radiation background around Haiyang NPP was carried out in an area covered 5 829.6km2.With the collected 116 111 data in earth surface,the project found out environmental radiation background measurements and the activity of natural 40K,238U (226Ra),and 232Th.It was concluded that the dose rate in the northwest area of the NPP is the highest,the middle and northeast area are higher while the southwest and north area are lower.The activity of manmade radionuclide 137Cs and 60Co are less than their detective limits and did not find out resoluble manmade radionuclide and out of control radioactive sources.Two airborne radiation anormaly was found aroused by higher natural radiation in geological environment.
