摘要: 分析了大亚湾核电基地运行以来核电基地外围环境空气、饮用水、水库水和海水以及厂界内地下水中3H活度浓度的历年变化趋势。结果表明,在气载放射性流出物排放的主导方位,随着大亚湾核电基地气载放射性流出物排放3H增加,空气监测点中3H活度浓度有所升高,与大亚湾核电基地的距离增加呈下降的趋势;基地外围环境水库水、饮用水的3H活度浓度目前处于本底水平;基地排放口周围海域海水3H活度浓度比本底水平有所升高,但多年来所有点位没有发现有3H的累积趋势。目前大亚湾核电站排放氚对环境和公众无影响。

Abstract: The trend of 3H concentration over the years since Daya Bay Nuclear Power Base runs was analyzed for ambient air, drinking water, reservoir water and sea water around the base and groundwaterin the base sector. It turns out that, in the prevailing direction of radioactive gaseous discharge, 3H concertration in ambient air at monitoring pointswas slightly increased with the radioactive gaseous discharge of the base increased. And with the distance from the base increased, a downward trend is exhibited. The 3H concentrations in drinking water and reservoir water around thebase are currently in background levels. For seawater around the base's outfall,3H concentration is slightly higher than the background level. However, no accumulative trend was observed for all monitoring points over the years. Currently the discharge of 3H from the base had no impact on the environment and public.
