Koliko sam ja uspeo da iskopam prirodni ugalj ima oko 1ppm (part per million) uranijuma, vise nego duplo torijuma. To znaci da ako sagorite sedam tona na minut to znaci da imate oko 7 grama uranijuma na minut, ili oko deset kilograma na dan. Veci deo toga ostaje u pepelu, dok se deo izbaci u cesticama u dimu.... Deset kilograma uranijuma i dvadeset pet kilograma torijuma DNEVNO. Neka je podatak netacan, nek je i deset kilograma GODISNJE, to je sumanuto.

U principu, ovo nije problem ukoliko termoelektrana ima propisne filtere - onda sav uranijum i torijum iz uglja ostanu u tim filterima.
Osim Uranijuma i Torijuma se u uglju nalaze i svi ostali radioaktivni elementi nastali radioaktivnim raspadanjem Uranijuma - dakle ima ih vise, a kolicine zavise od njihovog vremena polu-raspada.
Medjutim, kako u mnogim nerazvijenim zemljama TE nemaju propisne filtere, ili oni nisu ispravni verovatno se u vazduh ispusta radioaktivni materijal - sto je verovatno i jedan od razloga opadajuceg zdravlja u okolinama tih TE.

Citat:
On of the interesting facts associated with the debate over nuclear power is the amount of radiation emitted by burning coal. Typically a coal-fired power plant emits about 3.3 times the amount of radioactive material into the environment that a nuclear plant does for a similar amount of power produced.
This is due to the fact that coal contains radioactive material, mostly uranium and thorium, at about 4 parts per million. Now this does not seem like a lot until the quantity of coal a 1000 megawatt plant will burn in a day, around 11,000 tons, is considered. This works out to be roughly 40 kilos of radioactive material (88 pounds) each day. About 10% of this will be released to the atmosphere and the rest will end up in the ash pile and subject to weathering. If proper scrubbers are in place as little as 1% could reach the atmosphere, but this is still rather significant given the tonnage of coal burned for electric generation.
