A radionuclide is an atom (element) with an unstable nucleus (core). The nucleus of the atom has excess energy that is released by different types of radioactive decay. Radionuclides in our environment are produced by minerals in the Earth's crust, by cosmic rays hitting atoms in the Earth's atmosphere, and by human activities.
