2015-02-05 · Thorium (Th-232) itself is not fissile, meaning it can’t produce energy directly in a conventional reactor. But when Th-232 is irradiated with neutrons it transforms to a fissile isotope of uranium, U-233. To use thorium to produce energy, you first have to irradiate thorium in a reactor.

Siehe auch: Übersicht über die Thorium-Isotope. Allgemeine Daten Thorium-brenselssyklusen trenger ett nøytron for å omdanne thorium-232 til uran-233 og ett nøytron for å fisjonere (spalte) uran-233, for hver eneste nøytron-generasjon. Siden Eta og Alpha (som det sto om i del 4 av denne føljetongen) er det de er, er det i prinsippet mulig å breede i et termisk nøytronspektrum (altså med nøytroner med lav energi).

Thorium 232

External gamma exposure is not a major concern because thorium emits only a small amount of gamma radiation. Although thorium-229 has a much higher gamma component than either thorium-232 or thorium-230, thorium-229 comprises a very small fraction of natural thorium.

Thorium entering the bloodstream will become stored in the bone marrow, but the majority will become lodged in the kidney, which is the major site of toxicity. More than a year and a half are required to rid the body of an accidental high dose of thorium, after which time measurable uranium is present in the bone and kidney.

Thorium Isotopes. As thorium-232 undergoes radioactive decay, it emits an alpha particle, with accompanying gamma radiation, and forms radium-228. This

Torium (Th) är ett grundämne i det periodiska systemet med atomnummer 90 och atommassa 232,03806 u. Klicka här för mer fakta och data om grundämnet

Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnish es black when it is exposed to air, forming thorium dioxide; it is moderately hard, malleable, and has a high melting point. Thorium is generally a health hazard only if it is taken into the body. External gamma exposure is not a major concern because thorium emits only a small amount of gamma radiation. Although thorium-229 has a much higher gamma component than either thorium-232 or thorium-230, thorium-229 comprises a very small fraction of natural thorium. Thorium.
