【摘要】 田湾核电站环境监测系统于2003年底前建成,为了检验田湾核电站环境监测的仪器设备、规程文件、质控措施和人员的技术水平是否满足运行时的要求,扩大和改善运行前的环境本底数据,并通过实践的经验反馈发现存在的问题,提出改进方案和措施,田湾核电站在2004年对核电站周围进行了(运行前)的环境监测。本文主要介绍2004年环境监测的方案、质量保证和主要监测结果及其与2000年4月~2002年3月二年的本底调查结果的比较。2004年监测结果表明,除海水中137Cs活度浓度与本底调查有明显差异外,其余监测结果与本底调查结果基本吻合。更多还原

【Abstract】 Tianwan Nuclear Power Station（TNPS） carried out the pre-operation environmental monitoring around the nuclear power station in 2004,in order to check whether equipments,procedures,QC measures,the staff′s technology level can meet all the needs of normal operating conditions,to accumulate and improve the pre-operation environmental background data,to find the latent problems by practice and feedback,and to give a better scheme and improvement measures.This article introduces environmental monitoring program,quality assurance,main monitoring results and comparisons of these results and background investigation results during 2000.4～2002.3.The monitoring results show that the environmental background remains basically at the same level of background investigation except the activity concentration of（）¹³⁷Cs in the seawater samples.更多还原
