四川省嘉陵江及其部分支流水体放射性水平调查

摘要

Through the investigation of radioactive level of in Jialing River,Bailong River and Fu River from 2013 to 2014,obtained the radioactive level data of natural nuclide U,Th,226 Ra,and 40K,artificial nuclide 9o Sr,137 Cs and 3H,found out that the natural radioactive nuclide concentration of water in Jialing River,Bailong River and Fu River did not increase obvioulsy due to the development of the economic activity in the basin.The work provided precious basic data for nuclear emergency work and scientific research in our province.%通过2013年、2014年对嘉陵江、白龙江和涪江水体的放射性水平调查,得到了天然核素U、Th、226 Ra、40K和人工核素90Sr、137 Cs以及3H的放射性水平数据,发现嘉陵江、白龙江和涪江等江河水体中天然放射性核素浓度,并未因流域内经济活动的发展而出现明显的上升.此调查对四川省核应急工作以及科研工作提供了宝贵的基础性数据.
