Assessment of natural background gamma radiation levels in and around Loktak Lake of Manipur, India
Natural pollution level due to terrestrial gamma radiation was measured at about seventy different sites in and around the Loktak Lake of Manipur, India, using NaI (Tl) scintillator-based Micro-R-survey meter, and high purity germanium detector. The observed annual effective dose in this study area...

| description | Natural pollution level due to terrestrial gamma radiation was measured at about seventy different sites in and around the Loktak Lake of Manipur, India, using NaI (Tl) scintillator-based Micro-R-survey meter, and high purity germanium detector. The observed annual effective dose in this study area ranges from 0.3 to 1.2 mSvy−1 with an average value of 0.7 ± 0.1 mSvy−1, which is higher than world average value of about 0.4 mSy−1 reported by the UNSCEAR 2000. The soil analysis for 226Ra, 232Th, and 40K of this area gives an average concentration of 74.6 (38.9-126.0) Bq/kg, 112.1 (30.2–224.3) Bq/kg, and 792.9 (287.4–1194.8) Bq/kg, respectively. |
