In fact, they have been used routinely in medicine for more than 30 years.On average, one in every two Australians can expect at some stage in his or her life to undergo a nuclear medicine procedure that uses a radioisotope for diagnostic or therapeutic purposes.The occurrence of natural diamonds is remarkable and important to earth studies.
A radiopharmaceutical is a compound that has been labelled with a radioisotope and can then be traced with a gamma camera.
Different isotopes of the same element have the same number of protons in their atomic nuclei but differing numbers of neutrons.
They can also be defined as atoms that contain an unstable combination of neutrons and protons.
The radioactive decay process of each type of radioisotope is unique and is measured with a time period called a half-life.
Radioisotopes are an essential part of radiopharmaceuticals.
