Various industries produce concentrated radioactivity in their byproducts: Mining originating industries such as the coal industries, petroleum extraction and processing and natural gas, mining enrichment waste, phosphate, etc. They have been well known and widely investigated. The EPA describes NORM wastes from the mining and processing of three categories of metals: rare earth metals, special application metals and metals produced in bulk quantities by industrial extraction processes. In addition, NORM has a lot of negative effects on the natural resources (water supplies, soils, air, etc.) and living organisms (human, animals, plants, microorganisms etc.). In this study, we investigated NORM levels that originated from mining industry and their effect on drinking water supplies. NORM parameter of gross alpha and gross beta were measured that only a few of them were over the standard levels. © 2006.
