@Martin Alonzo ?? Thorium itself is radioactive, and emits radioactive Radon gas. "Possible disadvantages[edit] Some experts note possible specific disadvantages of thorium nuclear power:[29] Breeding in a thermal neutron spectrum is slow and requires extensive reprocessing. The feasibility of reprocessing is still open.[30] Significant and expensive testing, analysis and licensing work is first required, requiring business and government support.[17] According to a 2012 report by the Bulletin of the Atomic Scientists, about using thorium fuel with existing water-cooled reactors, it would "require too great an investment and provide no clear payoff," noting that "from the utilities’ point of view, the only legitimate driver capable of motivating pursuit of thorium is economics."[29] There is a higher cost of fuel fabrication and reprocessing than in plants using traditional solid fuel rods.[17] Thorium, when being irradiated for use in reactors, will make uranium-232, which is very dangerous due to the gamma rays it emits. This irradiation process may be altered slightly by removing protactinium-233. The irradiation would then make uranium-233 in lieu of uranium-232, which can be used in nuclear weapons to make thorium into a dual purpose fuel." Just a few facts about thorium-based nuclear power. Real seriously dangerous by-products are produced. Still, I prefer nuclear-produced power, and will not take a personal stand against it, in general! Frank
