Iaea thorium 232
Webb232 Th is the predominant isotope of natural thorium. If this fertile material is loaded in the nuclear reactor, the nuclei of 232 Th absorb a neutron and become nuclei of 233 Th.The half-life of 233 Th is approximately 21.8 minutes. 233 Th decays (negative beta decay) to 233 Pa (protactinium), whose half-life is 26.97 days. 233 Pa decays (negative beta … Webbför 2 dagar sedan · Naturally occurring radioactive material, such as potassium-40, polonium-210, thorium-232 and uranium-238 can be found in food and drinking water. …

Webb5 dec. 2012 · With thorium fuel, the presence of highly radiotoxic 232 U means that the spent fuel must be handled using remote techniques in heavily-shielded containment … Webb232 Th decays very slowly (its half-life is comparable to the age of the universe) but other thorium isotopes occur in the thorium and uranium decay chains. Most of these are short-lived and hence much more radioactive than 232 Th, though on a mass basis they are negligible. Thorium resource estimates [ edit]

WebbTh-232: 4055 Bq/g U-235: 80000 Bq/g U-238: 12300 Bq/g For each radionuclide above, the specific activity is for 100% pure material, therefore the conversion factor for a given percentage is 100 times less. For thorium the natural ratio ("Th-natural") is: Th [rad.act.] = 40.6 Bq/g per % Th Th [rad.act.] = 35.6 Bq/g per % ThO2 WebbThe element thorium (Th) has 90 protons in its nucleus. Naturally occurring thorium is 100% 232 Th. Its melting point is 2024 K and its boiling point is 5081 K. Thorium has been used to fuel over a dozen reactors in the past, significant among these were two light water breeder reactors at Shippingport.
Thorium-232 ( Th ) is the main naturally occurring isotope of thorium, with a relative abundance of 99.98%. It has a half life of 14 billion years, which makes it the longest-lived isotope of thorium. It decays by alpha decay to radium-228; its decay chain terminates at stable lead-208. Thorium-232 is a fertile material; it can capture a neutron to form thorium-233, which subsequently undergoes two successive beta decays to uranium-233, which is fissile. As such, it has been use…
