Levels of 14C in the Tree Rings in the Vicinity of Qinshan Nuclear Power Plant
摘要
Abstract
14C specific activities in the annual tree rings（corresponding to the years 1980—2009） from the Qinshan Nuclear Power Plant（Qinshan NPP） surroundings are presented.The tree rings sectioned from a pine tree which located 2 km away from the Qinshan NPP showed negligible enhanced 14C activity due to the operation of the Qinshan NPP Phase I.However,the data indicates a relative increase in the specific activity（2.6—63.4 Bq/kg C） after the operation of Qinshan NPP Phase II and Phase III.The enhanced values were primarily affected by the 14C discharged from Phase III（CANDU-type reactor）,and a good correlation between the annual 14C discharge and the 14C excess value was found.The excess14C acitivities declined after 2005 for improvement of the 14C pollutant management,and the 14C specific activity in 2009 was close to the background level.关键词
