Abstract:
Objective To investigate the food radioactivity levels in areas around the Xudabao nuclear plant before operation. Methods The food radioactivity levels were achieved by detecting samples collected within 30 km around the Xudabao nuclear power plant with a HPGe detector. Results The major radionuclides in food were 238U, 226Ra, 232Th, 40K and the man-made radionuclide of 137Cs. The average activity levels of natural 238U、226Ra、232Th、40K were(1.2 × 10−11 ± 2.6 × 10−11)、(9.2 × 10−12 ± 1.6 × 10−11)、(3.6 × 10−11 ± 6.5 × 10−12)、(9.0 × 101 ± 5.8 × 101)Bq/kg respectively. The average level of 137Cs in food was (1.2 × 10−12 ± 9.0 × 10−13)Bq/kg. Conclusion The man-made radionuclides were not detected except 137Cs in the collected food. The radioactivity concentrations were lower than the national standards. The effective dose for local residents by ingestion of 137Cs was around 6.0 × 10−12 µSv/a.
