The average radioactivity concentration of 226Ra, 232Th and 40K in Churchandpur was found as 39.9 (range: 30\u201356), 72.1 (range: 57\u201393) and 564.1 (range:360\u2013867) Bq\u00a0kg\u22121 respectively, whereas, in Ukhrul, average radioactivity for the same was found as 30.3 (range: 16\u201354), 54.2 (range:24\u201389) and 637.1(range:103\u2013901) Bq\u00a0kg\u22121, respectively. The calculated radioactivity parameters were compared with the world average values. The measured radium equivalent activity (Raeq), absorbed dose rate ($\\dot{\\mathrm D}$), annual effective outdoor dose(\u0116) and the external hazard index (Hex) were observed as 165 (range: 63.7\u2013234.8) Bq\u00a0kg\u22121, 77.6 (36.9\u2013108.0) nGy\u00a0h\u22121, 0.11 (0.05\u20130.13) mSv\u00a0y\u22121 and 0.5 (0.1\u20130.6), respectively.
