摘　　要：本文通过对黄河内蒙古段流域44个监测点位地表水、地下水、底泥及生物等样品中U、Th、Ra-226、K-40、Sr-90、Cs-137的放射性水平调查,发现黄河内蒙古段流域除灌区由于农业生产施肥造成K-40活度浓度水平较高外,其他区域天然及人工放射性均处于环境本底水平。The radioactivity level of U-238,Th-232,Ra-226,K-40,Sr-90 and Cs-137 in surface water,groundwater,sediment and biological samples from 45 monitoring points in the Yellow River basin within Inner Mongolia were investigated.The results show that the content of natural and artificial radioactive substances in the Yellow River basin within Inner Mongolia is at the environmental background level,except that the activity concentration of K-40 and the total radioactivity level are higher in the irrigation area due to agricultural production and fertilization.
