Western Australian mineral sands deposits contain up to 10% heavy minerals, of which 1-3% is monazite. This in turn typically contains 5-7% of radioactive thorium and 0.1-0.3% of uranium, which is barely radioactive. However, if decay products of either are present in the minerals, the radioactivity levels may be significant when the monazite

The story of thorium's mineral evolution provides an instruc-tive complement to that of uranium, because the elements are quite similar in the crystal chemistry of their relatively insoluble 4+ valence states, but Th does not adopt the distinctive highly soluble 6+ valence state of U.

In 1815, for example, Berzelius isolated a new element from a mineral sent to him from the Swedish mining town of Falun and named it thorium after the Scandinavian god of thunder, Thor.
