Abstract

Natural and fallout radioactivity were estimated in topsoil samples collected in eastern region of Shangrao Prefecture, China. The average activity concentrations of 238U, 226Ra, 232Th and 40K in the soil were nearly 2 times the world median value and Chinese average. The 137Cs activity concentration decreased compared with the previously reported value in the same region. The absorbed dose rate and annual effective dose rate estimated in the study area are found to be both higher than the world average values. 238U/226Ra and 232Th/226Ra activity ratios were also considered in this study.
