objective Monitoring of environmental radiation levels around the plant and the environment medium radioactive nuclide activity, and compared with before operation background and the related standards, monitoring the change of environmental radiation levels around the plant and the accumulation of radioactive nuclide, to assess the effects of a nuclear radiation emission on the surrounding environment. Methods based on relevant national radioactive testing standards and norms, gathering around the plant and contrast region respectively aerosols, atmospheric fallout in the environment and drinking water, total radiation level monitoring. Results ambient aerosols Ningde nuclear power station in 2013 totalα, β activity concentrations were 0.09 + / - 0.07 mBq/m3 and 1.03 + / - 0.67 mBq/m3, controlled area was 0.18 + / - 0.11 mBq/m3, 1.02 + / - 0.68 Bq/m3;Around the plant environmental atmospheric fallout of total α,β activity concentrations were 0.05 + / - 0.04 Bq/m2 ? d, 0.11 + / - 0.06 Bq/m2 ? d, controlled area was 0.14 + / - 0.08 Bq/m2, d, 0.20 +/ - 0.08 Bq/m2, d;Around the plant source of drinking water water activity concentration 0.004 Bq/Bq/L and 0.044 L, controlled area is 0.005 Bq/Bq/L and 0.067 L. Conclusion The total α, β radioactivity level have no statistical significance in Ningde Ningde nuclear power plant and in control areal .and compared with before running background value, also have no obvious change.
