A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is an atom that has excess nuclear energy, making it unstable.This excess energy can be either emitted from the nucleus as gamma radiation, or create and emit from the nucleus a new particle (alpha particle or beta particle), or transfer this excess energy to one of its electrons, causing that electron to be ejected as a conversion electron.Radionuclides are present in many homes as they are used inside the most common household smoke detectors.

In the presence of smoke some of the ions are neutralized, thereby decreasing the current, which activates the detector's alarm.Many of these radionuclides exist only in trace amounts in nature, including all cosmogenic nuclides.
