Thorium - an overview | ScienceDirect Topics
After that period, thorium uranium spent fuel is estimated to be 10,000 times less radiotoxic than spent fuel derived from a uranium open fuel cycle (Hargraves & Moir, 2010, p. 309). On the other hand, other long-lived radionuclides will be produced, including other isotopes of thorium …

Radionuclides (including Radon, Radium and Uranium) Hazard Summary Uranium, radium, and radon are naturally occurring radionuclides found in the environment. No information is available on the acute (short-term) noncancer effects of the radionuclides in humans.
Determination of 210Po and uranium in high …
Uranium isotopes 235 U and 238 U can be directly determined by ICP MS method with a detection limit of 0.01 ppb for 238 U. Prior to a selective determination of 210 Po, the majority of other naturally occurring α-emitting radionuclides (uranium, thorium and protactinium) can be stripped from this solution by their extraction with a 50% solution of HDEHP in toluene.

Decay chain - Wikipedia
18-03-2003 · For example, uranium-238 is weakly radioactive, but pitchblende, a uranium ore, is 13 times more radioactive than the pure uranium metal because of the radium and other daughter isotopes it contains. Not only are unstable radium isotopes significant radioactivity emitters, but as the next stage in the decay chain they also generate radon , a heavy, inert, naturally occurring radioactive gas.

Thorium reactor heeft nodige haken en ogen | De Ingenieur
Die belangstelling voor thorium heeft een even banale als dwingende achtergrond: de 37 kerncentrales die China nu in gebruik heeft, en de 20 die nu in aanbouw zijn, hebben allemaal uranium nodig. Het land beschikt echter nauwelijks over die grondstof. Thorium is daarentegen wel in …

Thorium vs Uranium – Energy Release per Fission. In general, the nuclear fission results in the release of enormous quantities of energy. The amount of energy depends strongly on the nucleus to be fissioned and also depends strongly on the kinetic energy of an incident neutron.

Thorium vs Uranium - Nuclear Power
Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature.This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of earth. Therefore 232 Th belongs to primordial nuclides.. 232 Th decays via alpha decay into 228 Ra .
