WebRadioisotopes are used to follow the paths of biochemical reactions or to determine how a substance is distributed within an organism. Radioactive tracers are also used in many medical applications, including both diagnosis and treatment. They are used to measure engine wear, analyze the geological formation around oil wells, and much more. WebThe only radioisotope that has consistently met the basic criteria is plutonium-238, which has a half-life of 88 years and a high power density, and has proven to be a very dependable and safe heat source on more than two dozen U.S. space missions over the past 50 years. In unlikely event of a mission accident, there is a potential for the ...
