Thorium plant at, IREL OSCOM produces thorium nitrate (mantle grade) from thorium concentrate/thorium oxalate obtained from the Rare Earths plant at Udyogamandal. The process involves external and internal exposure of workers due to the handling of radioactive material. Scientific management, involving safe handling of radioactive material and process modifications has been responsible to optimize the occupational exposures to low levels. The paper describes the various safety measures and process modifications that resulted in the per capita dose reduction, from 10.4 mSv to 3.6 mSv, during the last one decade. |
