Unlike natural uranium , natural thorium contains only trace amounts of fissile material (such as thorium 231), which are insufficient to initiate and sustain nuclear chain reaction. The thorium series is one of three classical radioactive series beginning with naturally occurring thorium-232.This radioactive decay chain consists of unstable heavy atomic nuclei that decay through a sequence of alpha and beta decays until a stable nucleus is achieved. Thorium-232 brytes ned sakte, og har en halveringstid som tilsvarer tre ganger jordas alder, men andre isotoper forekommer i nedbrytingen av uran. De aller fleste av disse har mye kortere halveringstider enn Th-232 og er derfor mye mer radioaktive. I forhold til Th-232 er forekomstene av disse ubetydelige. Anvendelse THORIUM 232 - From History to ReactorThis is a visual summary of all the information about thorium.Thorium is a weak radioactive element with atomic number 9 Thorium-232 of 232 Th is een onstabiele radioactieve isotoop van thorium, een actinide, met een zeer lange halveringstijd van ruim 14 miljard jaar.

Even ordinary glass can contain high-enough levels of potassium-40 or thorium-232 to be detectable with a survey instrument. Thorium is a weak radioactive element of the actinide series. It is chemically represented as Th with an atomic number of 90 and atomic weight of 232.03.

November, 23rd 2010 Serena Risica, Francesco Bochicchio and Cristina Nuccetelli Istituto Superiore di Sanità (National Institute of Health) Rome, Italy For at thorium-232 skal kunne brukes i en reaktor må det omvandles til den fisjonerbare nukliden uran-233, dette gjøres ved å sette inn et ekstra nøytron i thorium-232. Da får vi thorium-233 som er ustabilt og på et par timer gjøres om til Protactiniumet-233, som vil omgjøres seg til uran- 233 i løpet av et par måneder (Omtvedt 2008). 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.

If the daughter decays by beta emission, what is the Download scientific diagram | Thorium-232 decay series (The time associated with the respective radionuclide indicates the half-life). from publication: M. Omar, Answer to In the thorium decay series, thorium-232 loses a total of six alpha particles and four beta particles in a 10-stage proc To stop the Thorium-based nuclear reaction, just stop bombardment of Th-232 with neutrons, and the reactor "core" begins to immediately cool down.
