Därtill bildas 233U från 232Th som också fissioneras och ger ett energibidrag. SSM 2013:03. Page 30. 24. Tabell 4: Toriumreaktor med låganrikat 

Dec 5, 2012 As a by-product, the process also produces the highly radiotoxic isotope uranium -232. Because of this, producing uranium-233 from thorium 

If the radioactive decay of Thorium-(232) occurs, the first product obtained is See full answer below. Almost all thorium found in nature is the isotope thorium-232 (several other isotopes exist in trace amounts or can be produced synthetically). This slightly radioactive material is not fissile itself, but it can be transformed in a nuclear reactor to the fissile uranium-233. Such uranium-containing glass is often referred to as canary or vaseline glass.

Thorium - Th90. February 18 at 7:20 PM · +8. Ebe Physic added 12 new photos to the album: Thorium. October 29, 2016. Thorium thorium-232 requires a source of neutrons for the transmutation to take place, from a fissile material (such as uranium-235 or plutonium 239) or from an external source such as spallation neutrons. Thorium-232 appears in nature unmixed with isotopes, does not require enrichment for use as reactor fuel, and only needs The energies of electrons emitted after β decays are not listed here. 90-Th-232.

In general, naturally occurring thorium exists as Th-232, Th-230 or Th-228. Natural thorium consists almost to 100% by weight of the very long-lived isotope 232 Th (t ½ 1.405×10 10 y), which is the parent nuclide of the thorium decay series.

In thorium …isotopes, predominantly the very long-lived thorium-232 (1.40 × 10 10-year half-life), the parent of the thorium radioactive decay series. Other isotopes occur naturally in the uranium and actinium decay series, and thorium is present in all uranium ores. Thorium-232 is useful in breeder reactors because on capturing slow-moving neutrons Thorium 232 is the most common isotope of thorium in the nature. 232Th is a fertile isotope, but is not capable of undergoing fission reaction after absorbing thermal neutron.

Sammanfattning : Thorium is an element for possible use as nuclear fuel, because of the fertile property of Th-232, which could convert into U-233 after neutron 

Thorium-232. Atomic No. Radionuclide Class Table 1 Occupational Values Table 2 Effluent Concentrations Table 3 Releases to Sewers; Col. 1 Col. 2 Col. 3 Col. 1 Col. 2 Thorium 232 The Th232 Gamma Spectrum, has many peaks stretching out to 2.6 MeV, and it can be tricky to identify the correct peaks. Detectors smaller than 2" x 2" may have difficulty seeing the higher end gammas, which means you are only seeingt part of the spectrum. The most stable isotope, 232 Th, has a half-life of 14.05 billion years, or about the age of the universe; it decays very slowly via alpha decay, starting a decay chain named the thorium series that ends at stable 208 Pb. Thorium-232 is not a stable isotope. As thorium-232 decays, it releases radiation and forms decay products that include radium-228 and thorium-228.
