Apatite can contain trace amounts of radioactive elements, such as uranium, radium and thorium. Uranium radium and thorium are naturally occurring radioactive elements that are commonly found in the Earth’s crust. When apatite forms in geological environments where these radioactive elements are present, it can incorporate them into its crystal structure.
