| Abstract:: |
| Objective To evaluate the impacts of radioactivity in foods since begining of the operation of the Hongyanhe Nuclear Power Plant (HNPP). Methods The levels of radioactivity in foods collected within 30 km of HNPP from 2013 to 2020 were analyzed by comparison of the control samples and those collected before the operation. The impacts on the operation of the HNPP on foods were evaluated. Results The man-made radionuclides such as 131I, 134Cs, 60Co, 58Co, 110Agm were not found in food samples. The nautral radionuclides such as 238U, 226Ra, 232Th, 40K were at the normal levels, with the average levels of (0.088±0.053),(0.155±0.178),(0.314±0.388) and(81.3±18.1) Bq/kg(fresh weight) in foods, respectively. The average levels of man-made nuclide 137Cs in foods were (0.013±0.010) Bq/kg (fresh weight). There was no increase in radionuclide levels compared with the control samples and the samples before the operation. Conclusions The impacts on foods due to the operation of HNPP was not found. |
