Abstract

The activity concentrations of 238U, 232Th and 40K in riverbank soil along the Chao Phraya river basin was determined through gamma-ray spectrometry measurements made using a hyper-pure germanium detector in a low background configuration. The rangesof activity concentrarions were found to be 13.9 - 76.8, 12.9 - 142.9 and 178.4 - 810.7 Bq/Kg respectively. The anthropogenic radionuclide 137Cs was not observed in statistically significant amounts above the background level in the curremt study.
