  "term": "Radionuclide",
  "field": "Environment",
  "definition": "1. An unstable form of a chemical element that radioactively decays, resulting in the emission of nuclear radiation. Prolonged exposure to radionuclides increases the risk of cancer.\n\n2. A radionuclide is a radioactive element characterized according to its atomic mass and atomic number, which can be artificial or naturally occurring. Radionuclides have a long life as soil or water pollutants. Radionuclides cannot be destroyed or degraded; therefore, applicable technologies involve separation, concentration and volume reduction, immobilization, or vitrification.\n\n3. Any man-made or natural element which emits radiation in the form of alpha or beta particles, or as gamma rays.\n\n4. Radioactive particle, man-made (anthropogenic) or natural, with a distinct atomic weight number. Can have a long life as soil or water pollutant.\n\n5. Radioactive particle, man-made or natural, with a distinct atomic weight number. Emits radiation in the form of alpha or beta particles, or as gamma rays. Can have a long life as soil or water pollutant. Prolonged exposure to radionuclides increases the risk of cancer.\n\n6. Radioactive forms of elements. Radium-226, cesium-137, and strontium-90 are examples of radionuclides. They are unstable and decay to reach a more stable configuration.\n\n7. Type of atom which spontaneously undergoes radioactive decay. [40 CFR 61.101 (CFR 2013)]\n\n8. Radioactive forms of elements are called radionuclides. Radium-226, Cesium-137, and Strontium-90 are examples of radionuclides.\n\n9. Radioactive isotopes resulting from (1) the fission of heavy nuclei of elements such as uranium and plutonium, or (2) the reaction of neutrons with stable nuclei.\n\n10. Any man-made or natural element that emits radiation and that may cause cancer after many years of exposure through drinking water.",
