摘要
为了解与掌握黑龙江省水源水和末梢水的放射性水平,对全省典型地区的水源水和末梢水进行抽样调查。研究发现,黑龙江省经过水厂处理之后的末梢水中总α放射性和总β放射性基本符合我国国家标准要求。直接供饮用的地下水源水中的放射性比活度呈现季节性变化,丰水期总α放射性比活度要高于枯水期,丰水期总β放射性比活度低于枯水期。为客观评价黑龙江省水源水及自来水中总放射性水平提供参考。
In order to know the radioactive levels of source and peripheral water in Heilongjiang Province,a sampling survey on source and peripheral water in typical areas of the province was done.The research found that the totalαandβradioactivity in peripheral water after the disposal of water works in Heilongjiang Province basically meets the demand of national standard.Specific activity of radioactivity in direct drinking water in underground source represent seasonal changes.αspecific activity of radioactivity in wet seasons is higher than dry seasons,whileβspecific activity of radioactivity in wet seasons is lower than dry seasons.This provides reference for the evaluation of total radioactive levels of source and tap water in Heilongjiang Province.
