摘要:
为了解海南昌江核电厂周围海域放射性水平,两次海域放射性调查分别于2009年和2017年进行。两次调查的调查项目、范围、频次、站位、要素等均依据相关标准规范制定。调查中的采样、预处理和放化分析方法也参照了当时最新的标准规范要求。通过对调查结果的对比分析显示,两次调查中海水、沉积物、海洋生物的绝大部分测量结果基本处于同一水平,可认为海南昌江核电厂1、2号机组的运行未对周围海域环境放射性水平产生明显影响,建议在后续监测工作中进一步关注90Sr。

Abstract:
To acquire the marine radioactivity level around Hainan Changjiang NPP, two marine radioactivity surveys were conducted in 2009 and 2017. The medium, scope, frequency, site and item of two surveys were set according to officially issued standards or specifications. The methods of sampling, pretreatment and radiochemical analysis were also referred to the update standards related. The comparison result of two surveys show that the radioactivity levels in most of seawater, sediment and marine organism samples are not significantly different. It can be concluded that the operation of Hainan Changjiang NPP Unit 1 and 2 did not have an obvious influence on marine radioactivity level around the plant. It is suggested that 90Sr monitoring should be concerned in the future survey.
