What is thorium? Thorium is a naturally occurring radioactive metal that is found in soil, rock, and water. It is formed by the radioactive decay of uranium. Minerals such as monazite, thorite, and thorianite are rich in thorium and may be mined for the metal. Thorium has coloring properties that have made it useful in ceramic glazes.

Apr 24, 2017· Uranium, the 92nd element in the periodic table, is a heavy metal with a variety of uses. Uranium was first discovered by Martin Heinrich Klaproth in 1789 but rose to prominence in 1938 with the discovery of nuclear fission, in which an isotope of uranium, U235, is split at the atomic level, releasing a great amount of energy.

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 oceanfloor sediments, where their ratios are measured. The scheme has a range of several hundred thousand years.
