【摘要】 为评估开展第二次全国辐射环境水平调查的必要性,本文详细调研和统计了全国天然放射水平调查开展以来,历次辐射环境水平调查所涉及的监测对象(介质)、监测项目及点位覆盖情况。经对比分析发现,我国辐射环境水平调查存在空气和生物介质调查数据偏少、人工放射性核素调查不充分、海洋环境监测覆盖面不足、氡浓度调查不受重视和水体放射性水平调查需要进一步夯实等不足之处;我国辐射环境水平调查下一步的工作应以数据库建库,以及针对上述不足补充开展单项调查为重点,待时机成熟后再启动第二次全国性综合调查。更多还原

【Abstract】 Aiming to evaluate the necessity of carrying out the 2nd nationwide environmental radiation level survey,the environmental monitoring surveys carried out ever since the 1st nationwide natural radiation level survey were investigated,among which monitoring objects or environmental medias,monitoring items and the coverage of monitoring sites of each survey were analyzed. Several shortages were found,for example,data for air sample and biological sample are insufficient,activity concentration of artificial radionuclides needs to be further investigated,coverage of marine monitoring requires improvement,radon concentration survey wasn’t paid adequate attention,terrestrial aquatic radioactivity survey needs to be further strengthened, etc. In summary,in the nearest future,establishment of environmental survey database,correspondent surveys for compensating the previous shortages should be the focused. Therefore,the 2nd nationwide survey was not suggested to be carried out currently.更多还原
