| Abstract | The activity concentrations of the natural radionuclides were measured from the soil samples of East Khasi Hills District of Meghalaya, India, using gamma-ray spectroscopy. The range of the activity concentrations determined for$ ^{40}$K,$ ^{226}$Ra, and$ ^{232}$Th in Bq/kg was 96.6–518.0, 27.2–122.1, and 39.2–153.4, respectively, and their respective average values were 221.0, 45.9, and 68.7. The range of outdoor annual effective dose was 53.1–209.3 μSv/y, with an average value of 88.2 μSv/y. The values of radium equivalent activity $(Ra_{eq}$) ranged from 96.5 to 265.4 Bq/kg. Values of $Ra_{eq}$ from all the sampling locations were less than the recommended limit of 370 Bq/kg set by the Organization for Economic Cooperation and Development except in one location, Mylliem village. The study reveals that the soil samples from the selected, sampling villages, except Mylliem village, are safe and do not pose any significant radiological threat to population exposure. |
