Web6. Thorium and thorium / magnesium alloys are prone to corrosion if allowed to weather, resulting in a loose powdery oxide which can pose a contamination hazard. 7. Specialised chemical processing, such as that used to prepare laboratory compounds, can separate Th-232 from other non-thorium daughter nuclides resulting in a rather different Web5 Jul 2012 · it says that 79% of the time U-238 goes to the ground state of Th-234 emitting a 4.198 MeV alpha ray. But the difference between the ground state of U-238 and Th-234 is more than 4.198 MeV. What happened to the rest of the decay energy? Does it have anything to do with uncertainties? Thanks.
