Radioactive Wastes From Coal-fired Power Plants | US EPA

Coal is a fossil fuel used to produce power in the United States. Coal contains trace amounts of naturally-occurring radioactive elements. The process of burning coal at coal-fired power plants, called combustion, creates wastes that contain small amounts of naturally-occurring radioactive material (NORM).
