Throughout the countries of Central and Eastern Europe there was widespread mining and processing of uranium which has left a huge environmental and public health problem requiring urgent remedial action. The present paper outlines the situation from the perspective of the European Union by presenting a description of the
Average radiation exposure in the Australian uranium mining and milling industry is well below the relevant occupational exposure limit of 50 mSv per year. Workers exposure varies depending on what part of a uranium mining and milling operation they work in. Miners typically have exposures that are three times that of a processing workers.
