Radio-isotopes are a crucial component of the radiopharmaceuticals that are used. routinely in the clinics for the non-invasive diagnosis and treatment of various diseases. These radiopharmaceuticals are specific biological molecules tagged (or labelled) with. medical radioisotopes.
1 Naturally occurring and man-made radionuclides, also called radioactive isotopes or radioisotopes, are unstable, and emit radiation as they spontaneously disintegrate, or decay, to a stable state. 2  The radionuclide used almost always for the irradiation of food by gamma rays is cobalt-60.he Food irradiation process. The radiation used in processing materials is limited to radiation from high-energy gamma rays, X-rays and accelerated electrons.
