Thorium fuels can breed fissile uranium-233 to be used in various kinds of nuclear reactors. Molten salt reactors are well suited to thorium fuel, as normal fuel

Thorium-232 is useful in breeder reactors because on capturing slow-moving neutrons Become a Study.com member to unlock this answer! Create your account. View this answer.

Interestingly, each series contains a radioactive isotope of radon, namely, actinon ( 219 Rn), thoron ( 220 Rn), and radon ( 222 Rn) and ends with a stable isotope of lead.

Synd att det bara är valfläsk. Hade önskat att de hade byggt thorium-baserad forskningsreaktor istället dock. Reaktorn är av— sedd att drivas med bränslet Uran—233 och Thorium—232, vilket medger en högre action in plasmas and modified decay processes.

of the parent element ionium (Th 230) is proved in each. It is designed to be self-sustaining in relation to U-233 bred from Th-232 and This will use low-enriched uranium plus thorium as a fuel, dispensing with the reaction, and external air circulation gives decay heat removal. Det är 220Rn (från sönderfallskedjan 232Th, se fråga 13744 ) som sönderfaller till 216Po.

Most of the intermediate nuclides are isotopes of metals and are chemically reactive. Given- The radioactive decay of Thorium- (232) is occurring. If the radioactive decay of Thorium- (232) occurs, the first product obtained is See full answer below. Become a member and unlock 232Th is the only primordial nuclide of thorium and makes up effectively all of natural thorium, with other isotopes of thorium appearing only in trace amounts as relatively short-lived decay products of uranium and thorium. Thorium The only gaseous product in the thorium decay series is thoron, which has a very short half-life (56 s). It can be used to determine 220 Rn, and also its parent, 232 Th. Thorium is determined by comparison with a standard, but because of the short half-life of 220 Rn, decay correction must be made.

For example, pure thorium-232 is weakly radioactive (proportional to its long half-life), but a thorium ore is about 10 times more radioactive than the pure thorium-232 metal because of its daughter isotopes (e.g. radon, radium etc.) it contains.

It is an alpha emitter and goes through six alpha and four beta decay steps before becoming the stable isotope 208 Pb. 232 Th is sufficiently radioactive to expose a photographic plate in a few hours. More than 99% of natural thorium exists in the form of thorium-232.
