秦山核电基地外围水体环境中14C水平和分布
Concentration and Distribution of 14 C in Aquatic Envi ronment around Qinshan Nuclear Power Plant
摘要
Abstract
In order to study the concentration and distribution of 14 C in aquatic environ‐ment in the vicinity of Qinshan Nuclear Power Plant (NPP) after twenty years’ opera‐tion ,an apparatus extracting dissolved inorganic carbon from water was set up and applied to pretreat the water samples collected around Qinshan NPP .The 14 C concentra‐tion was measured by accelerator mass spectrometer (AMS) .The results show that the 14 C specific activities in surface seawater samples range from 196.8 to 206.5 Bq/kg ((203.4 ± 5.6) Bq/kg in average) ,which are close to the background .The 14C concen‐trations in cooling water discharged from Qinshan NPP are close to the 14 C values in near shore seawater samples out of liquid radioactive effluent discharge period .It can be further concluded that the 14 C discharged previously is diluted and diffused well ,and no 14C enrichment in seawater is found .Also ,no obvious increment in the 14C specific activities of surface water and underground water samples are found between Qinshan NPP region and the reference region .关键词
