Do coal-fired power stations produce radioactive

2021-5-5 · The 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.

Radioactivity of coals and ashes from Çatalağzi coal

2011-5-31 · The radioactive evaluation of the pulverised coal and ashes of Çatalağzı CFPP showed that the measured concentrations were above the world average value. The enrichment factors for the radioactivity of 232 Th, 226 Ra and 40 K from coal to fly ash were observed as 1.7, 2.24 and 2, respectively. Since the fly ash spewed out with the hot gases from the stack into the environment has
