Thorium is used in a wide array of products and processes, where its special properties make it useful when light or high temperature are involved. Handling and disposing of Thorium is a challenge, as it is radioactive and when it decays, and produces Radon gas (also historically called Thoron).

Thorium - an overview | ScienceDirect Topics

Thorium is present in seawater at only approximately 0.050 wppb, due primarily to the insoluble nature of its only oxide, ThO 2. Thus, the recovery of thorium from seawater is not a realistic option. Because 232 Th is the only isotope of natural thorium, there are no enrichment plant tails from thorium nuclear fuel.

Uranium and thorium | Geoscience Australia

Uranium and thorium are both silvery white-grey radioactive metals that corrode to black oxide in air. They are both malleable (can be pressed into shape) and ductile (can be beaten and drawn into a wire) and are very reactive and so cannot be found in the environment in their elemental forms.
