WebUranium and thorium are not stable. They break down in a process called radioactive decay. More than 99% of natural uranium exists in a form (isotope) called uranium-238 while more than 99% of natural thorium exists as thorium-232. These metals decay very slowly eventually to form lead. WebThe thorium fuel cycle is an alternative to uranium-plutonium. Thorium is widespread in the Earth’s crust and is known to occur in economically accessible deposits in many locations. Natural thorium is made up entirely of the isotope Th-232, which is fertile, but not fissile.

"WebThorium also decays in a series starting with the long-lived parent 232 Th with half-life 13.9 billion years and, after ten successive decays (Table 3), ends with a stable isotope of lead (208 Pb). Similar to the uranium series, many of these steps result in the emission of gamma rays with energies specific to the particular decaying radioisotope. " - Thorium half life vs uranium

WebUranium-238 has a half life of 4.51 billion years. This means that it would take billions of years for uranium-238 to decay into a ratio of half uranium-238 and half thorium-234 . [4] Uranium-235 (another naturally occurring isotope of uranium) has a shorter half life than uranium-238, that's only ~700 million years. WebUranium-232 has a half-life of 68.9 years and is a side product in the thorium cycle. It has been cited as an obstacle to nuclear proliferation using 233 U as the fissile material, because the intense gamma radiation emitted by 208 Tl (a daughter of 232 U, produced relatively quickly) makes the 233 U contaminated with it more difficult to handle.
