Abstract: 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.

Key words: Inner Mongolia, the Yellow River, radioactivity level, monitor
