Abstract/OtherAbstract:
Sediment samples from the Karnaphuli river estuary, nearshore, and off-shore regions off the coast of Chittagong in the Bay of Bengal were analyzed for the natural radioactivity contents of 232Th, 238U and 40K and anthropogenic radioactivity contents of 137Cs and 134Cs using HPGe gamma spectrometry, together with the measurement of sediment pH and grain size analyses of the collected samples. The activity of 232Th found in sediment ranged from 10.44 +/- 2.31 to 64.02 +/- 8.13 Bq kg(-1), 238U activity ranged from 5.87 +/- 1.21 to 27.85 +/- 1.71 Bq kg(-1), 40K activity from 118.28 +/- 19.70 to 608.21 +/- 75.70 Bq kg(-1), and the activity 137Cs ranged from 0.09 +/- 0.06 to 4.64 +/- 0.19 Bq kg(-1), no 134Cs radioactivity was detected at any of the sampling stations.
