How did thorium get its name
WebThe Earth's uranium had been thought to be produced in one or more supernovae over 6 billion years ago. More recent research suggests some uranium is formed in the merger of neutron stars. Uranium later became enriched in the continental crust. Radioactive decay contributes about half of the Earth’s heat flux. WebThe name comes from the Latin word "radius" which means ray. They named it after the rays that were emitted from the element. Isotopes There are four naturally occurring …

WebThorium-234 has a mean lifetime of 3 × 10 6 seconds, so there is equilibrium if one mole of 238 U contains 9 × 10 12 atoms of thorium-234, which is 1.5 × 10 −11 mole (the ratio of the two half-lives). Similarly, in an equilibrium in a closed system the amount of each decay product, except the end product lead, is proportional to its half-life. WebIf its a bit less, then it would still be closer to the Thorium in overall warmth than the Cerium but a few ounces lighter. I do wonder if it is more of a replacement for the Thorium AR as they have it listed as an AR weight jacket and there is quite a bit of overlap between the two. Also I don't see the Thorium on the main site anymore.
