half life

half life
the half life of a radioisotope can actually varie from seconds to billions of years. . The half-life of an atom is the amount of time it takes for half of the atom in a sample to decay. The half-life for an isotope is always the same. This shows the radiographer who works with your radioisotope the amount of radiation the source in the camera. This also used to tell the age of historic items this technique is known as carbon dating
cat scan
uses radiation imaging to produce a 3D image of the functions in your body
carbon 11
why nuclear medicine
Nuclear medicine specialists use safe, painless, and cost-effective techniques to image the body and treat disease. Nuclear medicine imaging is unique because it provides doctors with information about both structure and function it is a way to gather medical information that would otherwise be unavailable. Nuclear medicine imaging procedures often identify abnormalities very early in the progress of disease
PET
This method produces images of the body by detecting the radiation substances. These substances are injected into the body and usually tagged with radioactive atoms such as carbon 11. These radioactive atoms are formed by bombarding normal chemicals with neutrons to create short-lived radioactive isotope. PET detects the gamma rays given off at the site were a positron emitted from the radioactive substance
