Radiological environmental impact assessment of the proposed mineral separation projects of M/S Indian Rare Earths Ltd., at Ayiramthengu and Kudiraimozhi

Abstract

Pre-operational radiological monitoring was carried out at the proposed mineral separation project sites of Indian Rare Earths Ltd., at Ayiramthengu in Kollam Dist. (Kerala) and Kudiraimozhi at Chidambaranar Dist. (Tamil Nadu) and the nearby environment. Radiation levels in the project area ranged from 300 to 1400 nGy hr{sup -1} and the long lived activity in air samples were less than 10{sup -4} Bq m{sup -3}. The {sup 228}Ra levels in drinking water in the project area were less than 0.01 Bq l{sup -1}. Assessment of radiological environmental impact on the basis of the monitoring data and experience gained from the operations of the existing mineral separation plants indicate that there is a net reduction in the per capita environmental radiation exposures by about 4 mSv at Ayiramthengu and 2 mSv at Kudiraimozhi.
