摘要: 通过2018—2022年对台山地区大气气溶胶总α和总β放射性水平监测得知,气溶胶中总α、总β变化与台山核电运行没有明显的相关性;气溶胶中总α、总β活度浓度大小与尘重相关,尘重越大,总α、总β活度浓度越大;总α、总β活度浓度变化有明显的季节性特征,表现出冬季高、夏季低的情况,气溶胶总β/总α比值表现出夏季高、冬季低的特点。

关键词: 总α, 总β, 总β/总α比值, 气溶胶, 台山核电

Abstract: Based on the monitoring data of total α and total β radioactivity levels of atmospheric aerosols in Taishan area from 2018 to 2022, there is no obvious correlation between the total α and total β in aerosols and the operation of Taishan nuclear power plant. The activity concentration of total α and total β in aerosols is related to dust weight. The greater the dust weight, the higher the activity concentration of total α and total β. The activity concentrations of total α and total β have obvious seasonal characteristics, which are high in winter and low in summer. The total β to total α ratio of aerosol is high in summer.

Key words: Total α, Total β, Total β to total α ratio, Aerosol, Taishan NPP
