Ratio Of Thorium To Uranium In Zircon Sand

Where can I find all the details about the thorium scam in Zircon Hyperleap

Why Thorium is important Thorium might be the magic bullet for our energy problems In future we may see thorium based nuclear reactors which can put an end to the energy crisis in world and may be wars which are caused due to it Few Reasons Monazite is a chemically unreactive mineral that is found as yellow or brown sand its low reactivity makes it difficult to extract thorium from it Allanite chiefly silicates hydroxides of various metals can have 01 2 thorium and zircon chiefly zirconium silicate ZrSiO 4 up to 04 thorium

Th ThoriumMineral Sands NORM Appendix World Nuclear Association

Th Thorium Introduction Thorium is a member of the actinide series of elements along with U and the human made elements such as Pu The element has an atomic number of 90 an atomic mass of 232 one main oxidation state 4 and one naturally occurring isotope 232Th Like U Uranium thorium dating is commonly used to determine the age of calcium carbonate materials such as speleothem or coral because uranium is more soluble in water than thorium and protactinium which are selectively precipitated into ocean floor sediments where their ratios are measured The scheme has a range of several hundred thousand years
