Fly ash radioactive
Fly ash is a light colored, fine particle waste that resembles a powder. The majority of coal combustion wastes are fly ash. Bottom ash is a larger particle size then fly ash and is a heavier waste that resembles a mix of sand and small rocks. Just over 10% of coal combustion waste is bottom ash.

WebThe radioactivity comes from the trace amounts of uranium and thorium contained in coal. These elements have been trapped in the Earth’s crust since its formation and are usually in concentrations too low to pose any serious threat. But the burning of coal produces fly ash, a material in which the uranium and thorium are much more concentrated. http://www.dirtcheapbuilder.com/Articles/Building_Questions/Fly_Ash.htm
