Examples
-
Myocardial Perfusion Imaging (MPI) uses thallium-201, chloride, or technetium-99m and is important for detection and prognosis of coronary artery disease.
-
The reactors produce material called molybdenum-99 that decays into technetium-99m, which is the most commonly used medical isotope in the U.S.

-
The radioisotope most widely used in medicine is technetium-99m, employed in some 80% of all nuclear medicine procedures — 70,000 every day.
-
Thus, technetium-99m will remain radioactive for 60 hours, and iodine-131 will remain radioactive for 3 months.
-
For example, technetium-99m and iodine-131, which are used in nuclear medicine, have 6-hour and 8-day half-lives, respectively.
-
Ionizing radiation can also come from industrially produced radioactive materials (such as iridium-192); nuclear medicine (such as thyroid cancertreatment with iodine-131 and thyroid scans using iodine-125, or bone scans using technetium-99m); biological and medical research using carbon-14, tritium, and phosphorus-32; the nuclear fuel cycle (producing fission products such as cesium-137 and activation products such as cobalt-60); and production and testing of nuclear weapons.
-
While Chalk River produces the cheapest isotope, molybdenum-99, from which technetium-99m is easily extracted on-site at a hospital, there are other sources which, though more expensive, are available for medical procedures.

-
Mo-99 decays into technetium-99m, an isotope used in about 85 percent of all nuclear medicine procedures, including evaluation of the heart, kidneys, lungs, liver, spleen, bones and blood flow.

-
The project is one of four that the federal government announced in January in its quest to find a new source of technetium-99m - the most widely used isotope for medical imaging.
-
About 80 per cent of all medical radioisotope tests-from cardiac perfusion tests to bone scans for cancer-require technetium-99m.
