A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is an atom that has excess nuclear energy, making it unstable.
Radioactive waste is hazardous to most forms of life and the environment, and is regulated by government agencies in order to protect human health and the environment.he radioactivity of all nuclear waste diminishes with time. All radionuclides contained in the waste have a half-life âthe time it takes for half of the atoms to decay into another nuclide âand eventually all radioactive waste decays into non-radioactive elements (i.e., stable nuclides).
