Noun
radionuclide (plural radionuclides)
(physics) a radioactive nuclide
A synthetic radioisotope is a radionuclide that is not found in nature: no natural process or mechanism exists which produces it, or it is so unstable that it decays away in a very short period of time. Source: Internet
Gamma rays, emitted indirectly by a positron-emitting radionuclide (tracer), are detected in positron emission tomography (PET) scanners used in hospitals. Source: Internet
However, in a few cases of odd-proton, odd-neutron radionuclides, it may be energetically favorable for the radionuclide to decay to an even-proton, even-neutron isobar either by undergoing beta-positive or beta-negative decay. Source: Internet
There are two types of radionuclide scans that are used for determining the site of gastrointestinal bleeding; a Meckel's scan, and a tagged red blood cell (RBC) scan. Source: Internet
Tritium is considered a weak radionuclide because of its low-energy radioactive emissions ( beta particle energy up to 18.6 keV). Source: Internet
This is when radionuclide scans and visceral angiograms may be helpful. Source: Internet
