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.
Radiation is used in nuclear medicine and radiology. In nuclear medicine, radioactive materials known as radioisotopes, or radiopharmaceuticals, are introduced into the body. In radiology, X-rays enter the body from outside. According to the Center for Nuclear Science and Technology Information, about one-third of all procedures used in modern hospitals involve radiation or radioactivity.
