Lire particulièrement les commentaires sur le CE Journal :
Coal contains uranium, thorium, radium, radon and other radioactive elements at typical concentrations of several parts per million, ranging up to 50 parts per million or more [see references given below]. […]. The amount of radioactive uranium and thorium discharged by U.S. coal-fired plants is roughly 3000 tons per year: U.S. coal-fired electrical plants consumed 1.04 billion tons of coal in 2006. McBride et al (previous paragraph) estimate that U.S. coal contains, on average, 1 part per million uranium and 2 parts per million thorium.
During 1996, the most recent year for which ash statistics are currently available, the electrical utility industry in the United States generated approximately 53.5 million metric tons (59.4 million tons) of coal fly ash Fly ash is also disposed of in landfills and abandoned mines and quarries
coal fired electricity has increased, as a direct result of Al Gore preventing more nuclear power
per watt generated a coal burning plant generates roughly twice as much uranium as a nuclear plant
