WebThe gas thoron, or thorium emanation, is an isotope of radon ( 86 Rn 220) which decays by α emission and has a half life of 55.6 seconds. 2 Using an emanation electroscope, we observe the radioactive decay of thoron (separated from all its parent substances) by the progressive decrease of ionization in the air around the thoron. WebAug 31, 2024 · Something to consider when comparing Thorium and Uranium as energy sources is that Uranium-233 (the main, dangerous byproduct of Thorium energy generation) has a half-life of only 300 years, which is admittedly quite a long time, but is nothing when you compare it to the several 10,000 - 20,00 years needed for Uranium-based nuclear … tweed check suitWebJun 23, 2011 · All other issues aside, thorium is still nuclear energy, say environmentalists, its reactors disgorging the same toxic byproducts and fissile waste with the same … tweed chiropractic hawick

"WebUsing thorium does not eliminate the problem of long-lived radioactive waste. Fission of thorium creates long-lived fission products including technetium-99 (half-life of over 200,000 years). Without reprocessing, thorium-232 is itself extremely long-lived (half-life of 14 billion years) and its decay products will build up over time in irradiated fuel. " - Thorium waste half life
