WebFission track. Uranium is present in many different rocks and minerals, usually in the form of uranium-238. This form of uranium usually decays into a stable lead isotope but the uranium atoms can also split – a process known as fission. During this process the pieces of the atom move apart at high speed, causing damage to the rock or mineral.
