April 15, 2017. Radioactivity in minerals are caused by the inclusion of naturally-occurring radioactive elements in the mineral’s composition. The degree of radioactivity is dependent on the concentration and isotope present in the mineral. For the most part, minerals that contain potassium (K), uranium (U), and thorium (Th) are radioactive.

· For the most part, minerals that contain potassium (K), uranium (U), and thorium (Th) are radioactive. There are four main radioactive isotopes that have lasted as long as the Earth: Uranium-239 (over 99% of all uranium) with a half-life of 4.5 billion years. Uranium-235 (less than 1% of all uranium) with a half-life of 700 million years.
