Abstract
This is the first attempt to generate baseline data on the level of Naturally Occurring Radioactive Materials, (NORMs) 238U, 232Th and anthropogenic radionuclide, 137Cs in surface soil of Indian Sundarban. The activities of 238U and 232Th vary from 39.9 ± 2.4 to 57.9 ± 2.5 Bq kg−1 and 47.3 ± 2.4 to 64.8 ± 3.1 Bq kg−1 with mean of 48.7 ± 2.8 Bq kg−1 and 58.3 ± 3.3 Bq kg−1 respectively. The corresponding median values are 46.7 and 59.9 Bq kg−1. The close proximity of mean and median values indicates normal distribution of 238U and 232Th. In most of the samples, anthropogenic 137Cs activity has been found below detection limit (BDL). © 2016, Akadémiai Kiadó, Budapest, Hungary.
