Situation and trend of y nuclide radioactivity in aerosols in the surrounding environ-ment of Fuqing Nuclear Power Plant
In order to grasp the activity concentration level and change trend of the important γ-nuclides radionuclides in the aerosol of the environmental medium,since May 2015,the Qianxue,Dongyuan and Xiazhai three sites that in the domi-nant wind around the Fuqing Nuclear Power Plant downward have been conducted.The aerosols at the points were sampled and monitored monthly,and the results showed that artificial y nuclides including manganese-54,cobalt-58,cobalt-60,zir-conium-95,iodine-131,cesium-134,cesium-137 and cerium-144 were not detected;the activity concentration level of beryllium-7 nuclides did not change significantly.Beryllium-7 activity concentration varies with the seasons,low in sum-mer and autumn,high in spring and winter.Compared with the background investigation and monitoring results before oper-ation,the magnitude of the monitoring data is basically the same,indicating that the nuclear power plant has not caused ob-vious radiation impact on the surrounding environment since its operation.
