Stable isotopes of an element do not change over time. Atoms of unstable isotopes â also called radioisotopes--change into other elements over time through radioactive decay. Radioisotopes are used in many medical imaging and diagnostic procedures, with the isotope Tc-99m being used in 80 percent of tests.
On average, every Australian can expect to have a nuclear medicine procedure that uses a radioisotope for diagnostic or therapeutic purposes at some stage in their life. Nuclear medicine and radiology are the medical techniques that involve the use of radiation or radioactivity to diagnose, treat and prevent disease.While radiology has been used for close to a century, the term nuclear medicine began to be used around 50 years ago.Discover more.uclear power has been in use for decades and is one of the fastest growing energy options for countries seeking energy security and low-emission energy solutions. Globally nuclear power is the only proven base-load energy option available that has low carbon-dioxide emissions.
