How threatening it might sound, nuclear medicine is a very common type of treatment, as “On average, one in every two Australians can expect at some stage of his or her life to undergo a nuclear medicine procedure,” (Australian Nuclear Science and Technology Organization). It may come as a surprise, but these include Nuclear Imaging such as MRI (Magnetic Resonance Imaging), Pet scans, CT (Computerized Tomography) CAT (Computerized Axial Tomography). And no it is not
A green liquid in a capsule that is exhaling green visible gas Nuclear Imaging works on the principle of radiation (which is invisible by the way) and how to detect radiation. A radioisotope tracer is inserted into a chemical prevalent in your body like glucose. It consists of carrier molecules bonded to a radioactive atom that emits radiation, which is detected by a gamma camera. Radiation such as gamma radiation occur when the nucleus of an atom instable. This occurs when the proportion of neutrons and protons are not lying on the band of stability, which consists of stable nucleus configurations in relation to the atomic number (as seen below).

Atoms along the band of stability are assumed to contain enough energy within the nucleus to hold it together. This energy called the nuclear binding energy has yet to be discovered and is just a scientific assumption to explain why the like charge protons are not repelling each other. Atoms which don’t have substantial nuclear binding energy are generally…
