摘要：
The present study attempts to quantitatively estimate total potassium content in soil samples collected from different areas of Indian Sundarbans by gamma-spectrometry, exploiting the radiogenic properties of potassium and by wavelength dispersive X-ray fluorescence technique. The elemental K concentration varied in between 2.08 +/- 0.05 and 3.46 +/- 0.06% in the soil samples. Besides estimation of total potassium, the activity of K-40 was also estimated in the same soil samples and found to be in the range of 532 +/- 8.9 to 1043 +/- 13.2 Bq kg(-1).
