However, the main radioisotopes such as Tc-99m cannot effectively be produced without reactors.* Radioisotopes are an essential part of medical diagnostic procedures.In combination with imaging devices which register the gamma rays emitted from within, they can study the dynamic processes taking place in various parts of the body.This has led to its common use in developed countries where the probability of anyone having such a test is about one in two and rising.Every organ in our bodies acts differently from a chemical point of view.A positron-emitting radionuclide is introduced, usually by injection, and accumulates in the target tissue.

Five Nobel Laureates have been closely involved with the use of radioactive tracers in medicine.

In developed countries (a quarter of the world population) about one person in 50 uses diagnostic nuclear medicine each year, and the frequency of therapy with radioisotopes is about one-tenth of this.

Feb 12, 2014. This is important. For carbon-14 radiometric dating to be accurate, a fossil or artifact must be buried to avoid exposure to recently fixed radioactive carbon. The term 'half-life' refers to the amount of time it takes for half of a sample's radioactive isotopes to turn into a stable isotopes. We can determine the.… continue reading »
