Best Answer

The term radionuclide is one we apply to any atom with an unstable atomic nucleus. It's the correct term for radioisotope. These atoms are radioactive, and emit radioactivitywhen they undergo radioactive decay. There are unstable configurations of every element, and a few elements have no stable nuclear configurations at all. These include technetium, promethium, and also bismuth and all the elements with an atomic number greater than that of bismuth, which is 83.

What is radionuclide scanning?

Radionuclide scanning-- Diagnostic test in which a radioactive dye is injected into the bloodstream and photographed to display internal vessels, organs and tissues.


How do nuclear scans work?

For most nuclear imaging studies, radionuclide is injected into the patient and the images are taken with a gamma camera suspended above the patient who will be lying on a table. The camera detects the gamma rays emitted from the radionuclide in the patient's body and uses this information to produce an image that shows the distribution of the radionuclide within the body. The image is recorded on film and is called a radionuclide scan.

What are some environmental concerns about using the radioisotope iodine?

Iodine collects in the thyroid. If there is a radionuclide of iodine "loose" then we might end up ingesting it and having it collect in our thyroid. The radionuclide would sit there and irradiate us. That's not good. It's a bad idea to have radioactive iodine in the environment.
