How it works: We use thorium (in thorium oxide) to generate thoron. The sequence of decays is known as the Thorium-232 series and goes as follows:

WebThorium is slowly attacked by water but, except for hydrochloric acid, does not dissolve readily in most common acids. Uranium and thorium are not stable. They break down in a process called radioactive decay.
