- Radionuclide - Wikipedia
A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess numbers of either neutrons or protons, giving it excess nuclear energy, and making it unstable
- Radionuclides | US EPA
Learn the Radiation Basics Every radionuclide emits radiation at its own specific rate, which is measured in terms of half-life Radioactive half-life is the time required for half of the radioactive atoms present to decay Radioactive decay is when a radioisotope transforms into another radioisotope; this process emits radiation in some form
- What are radionuclides? Uses and dangers - Nuclear energy
A radionuclide is an unstable nuclide that, therefore, degenerates by emitting ionizing radiation Types and uses of radioisotopes
- Radionuclides | U. S. Geological Survey - USGS. gov
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
- Radionuclides (radioactive materials) | Chemical . . .
Radionuclides (or radioactive materials) are a class of chemicals where the nucleus of the atom is unstable They achieve stability through changes in the nucleus (spontaneous fission, emission of alpha particles, or conversion of neutrons to protons or the reverse)
- What is Radionuclide – Radioisotope – Definition
These nuclides are known as radionuclides (radioactive nuclides) or radioisotopes (radioactive isotopes) Radiation Dosimetry In nuclear physics and nuclear chemistry, the various species of atoms whose nuclei contain particular numbers of protons and neutrons are called nuclides
- Radioactive isotope | Description, Uses, Examples | Britannica
A radioactive isotope, also known as a radioisotope, radionuclide, or radioactive nuclide, is any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays

Each page contains information about the radionuclide, how it moves through the environment, where you will find it (the radiation source) and potential health effects
