| 中文摘要: |
| 通过2011—2013年对田湾核电站厂区及周围环境大气气溶胶中总α、总β放射性水平的监测，结果表明：该核电站厂区及周围环境大气气溶胶中总α、总β放射性浓度范围分别为0.023 mBq/m3～0.296 mBq/m3、0.240 mBq/m3～2.460 mBq/m3,放射性水平在本底范围内，未见明显差异；总α、总β放射性水平波动受气象条件影响，呈季节性变化特征。 |
| 英文摘要: |
| The total alpha and total beta radioactivity level of the atmospheric aerosol were monitored in 2011—2013 in Tianwan nuclear power plant and the surrounding area. The results showed that the total alpha and total beta radioactive concentration range of the atmospheric aerosol in nuclear power plant and the surrounding area was 0.023 mBq/m3 to 0.296 mBq/m3, 0.240 mBq/m3 to 2.460 mBq/m3, respectively, indicating that the radioactivity remained at background level,and had no significant difference. Total alpha and total beta radioactivity fluctuate with the meteorological conditions, possessing a seasonal variation characteristic. |
