摘要
为了取得苏州市地面土壤地质环境的eU、K、eTh含量背景值,提供辐射环境参照基准,进行环境天然放射性水平评价,使用FD-3022微机四道^y能谱仪直读地面土壤eU、K、eTh的含量。
This research aims to evaluate the radiological background level of Suzhou by detecting and analyzing the elemental concentrations of thorium,uranium and potassium in surface soils respectively and to provide the radiological environmental background information for further researches.Natural radionuclide concentrations in surface soils of Suzhou were measured by using a portable FD-3022 NaI(TI) detector.
