Radioactive contaminants found in coal ash

A new study has found radioactive contaminants in coal ash from all three major US coal-producing basins. Levels of radioactivity in the ash were five to eight times higher than in normal soil or in the parent coal itself. This finding raises concerns about the environmental and human health risks posed by coal ash, which currently is unregulated and is stored in coal-fired power plants' holding ponds and landfills nationwide.
