The radioactivity concentration and radiological parameters have been assessed in soil samples collected from Thoubal and Imphal East districts in Manipur, India, using a High-Purity Germanium (HPGe) detector. The range of activity concentration of 226Ra, 232Th, and 40K in the soil from the studied areas varies from 26 Bq/Kg (Heirok) to 132 BqKg-1(Porompat), 22 Bq/Kg (Yairipok Khoirom) to 212 Bq/Kg (Porompat), and 451 Bq/Kg (Thoubal Bazar) to 1819 Bq/Kg (Lamlai Bazar) with overall average values of 70 Bq/Kg, 90 Bq/Kg, and 895 Bq/Kg, respectively. The Radium equivalent activities (Raeq) have been evaluated in soil samples to assess the radiation hazard. The corresponding absorbed dose rate, annual effective dose, and external radiation hazard index in the study area range from 56.9 to 264.9 nGy/h, 0.3 to 1.6 mSv, and 0.3 to 1.5, with an average value of 127.7 nGy/h, 0.8 mSv/y, and 0.7, respectively.
