- Radionuclide - Wikipedia
A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that is unstable and known to undergo radioactive decay into a different nuclide, which may be another radionuclide (see decay chain) or be stable
- Radionuclides | US EPA
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 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
- Radionuclide Scanning - Harvard Health
A radionuclide scan is an imaging technique that uses a small dose of a radioactive chemical (isotope) called a tracer that can detect cancer, trauma, infection, or other disorders In a radionuclide scan, the tracer either is injected into a vein or swallowed
- What are radionuclides? Uses and dangers - Nuclear energy
A radioactive nuclide or radionuclide is an unstable nuclide and therefore degenerates by emitting ionizing radiation
- Radionuclides (radioactive materials) | Chemical Classifications . . .
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)
- 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
- What is Radionuclide – Radioisotope – Definition
Each radionuclide has its own particular half-life that never changes, regardless of the quantity or form of the material (i e , solid, liquid, gas, element or compound) or its past history
