Radioactive Elements in Coal and Fly Ash:
Radioactive elements from coal and fly ash may come in contact with the general public when they are dispersed in air and water or are included in commercial products that contain fly ash. The radiation hazard from airborne emissions of coal-fired power plants was evaluated in a series of studies conducted from 1975–1985.
