  2. Incompatible element - Wikipedia

    en.wikipedia.org/wiki/Incompatible_element

    In petrology and geochemistry, an incompatible element is one that is unsuitable in size and/or charge to the cation sites of the minerals in which it is included. It is defined by a partition coefficient between rock-forming minerals and melt being much smaller than 1.

  3. Naturally occurring radioactive material - Wikipedia

    en.wikipedia.org/wiki/Naturally_occurring...

    Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium and any of their decay products, such as radium and radon.

  4. List of countries by thorium resources - Wikipedia

    en.wikipedia.org/wiki/List_of_countries_by...

    Thorium resources are the estimated mineral reserves of thorium on Earth. Thorium is a future potential source of low-carbon energy. [1] Thorium has been demonstrated to perform as a nuclear fuel in several reactor designs. [2] [3] It is present with a higher abundance than uranium in the crust of the earth. Thorium resources have not been ...

    en.wikipedia.org/wiki/Occurrence_of_thorium

    Monazite contains 2.5% thorium, allanite has 0.1 to 2% thorium and zircon can have up to 0.4% thorium. [2] Thorium-containing minerals occur on all continents. [3] [4] [5] Thorium is several times more abundant in Earth's crust than all isotopes of uranium combined and thorium-232 is several hundred times more abundant than uranium-235. [6]

    Both (real) elements cobalt and thorium can be used in nukes to increase fallout, which agrees with the sense in which "Cobalt Thorium G" is used in the movie. In the "Wages of Fire" episode Big Guy and Rusty the Boy Robot, it is revealed that the BGY-11 is powered by a Cobalt Thorium G power core. Coaxium Star Wars

  7. Thorium-232 - Wikipedia

    en.wikipedia.org/wiki/Thorium-232

    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 used in the thorium fuel cycle in nuclear reactors; various prototype thorium-fueled reactors have been designed. However, as of 2024, thorium fuel has ...

  8. Xenotime - Wikipedia

    en.wikipedia.org/wiki/Xenotime

    Xenotime is a rare-earth phosphate mineral, the major component of which is yttrium orthophosphate (Y P O 4).It forms a solid solution series with chernovite-(Y) (Y As O 4) and therefore may contain trace impurities of arsenic, as well as silicon dioxide and calcium.

  9. Technetium - Wikipedia

    en.wikipedia.org/wiki/Technetium

    Naturally occurring technetium is a spontaneous fission product in uranium ore and thorium ore (the most common source), or the product of neutron capture in molybdenum ores. This silvery gray, crystalline transition metal lies between manganese and rhenium in group 7 of the periodic table , and its chemical properties are intermediate between ...
