However, the 231 Pa (with a half-life of 3.27 × 10 4 years) formed via (n,2n) reactions with 232 Th (yielding 231 Th that decays to 231 Pa), while not a transuranic waste, is a major contributor to the long-term radiotoxicity of spent nuclear fuel. While 231 Pa can in principle be converted back to 232
In enzymology, an alpha,alpha-trehalose-phosphate synthase (UDP-forming) (EC 2.4.1.15) is an enzyme that catalyzes the chemical reaction UDP-glucose + D-glucose 6-phosphate ⇌ {\displaystyle \rightleftharpoons } UDP + alpha,alpha-trehalose 6-phosphate
Uranium-232 (232 U) is an isotope of uranium.It has a half-life of around 69 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.
The most stable isotope is 231 Pa with a half-life of 32,760 years, 233 Pa with a half-life of 26.967 days, and 230 Pa with a half-life of 17.4 days. All of the remaining radioactive isotopes have half-lives less than 1.6 days, and the majority of these have half-lives less than 1.8 seconds.

Thorium (90 Th) has seven naturally occurring isotopes but none are stable. One isotope, 232 Th, is relatively stable, with a half-life of 1.405×10 10 years, considerably longer than the age of the Earth, and even slightly longer than the generally accepted age of the universe.
