radiochemistry, chemistry of radioactive substances (see radioactivity radioactivity, spontaneous disintegration or decay of the nucleus of an atom by emission of particles, usually accompanied by electromagnetic radiation . The energy produced by radioactivity has important military and industrial applications. ..... Click the link for more information. ). Radioactive isotopes radioactive isotope or radioisotope, natural or artificially created isotope of a chemical element having an unstable nucleus that decays, emitting alpha, beta, or gamma rays until stability is reached. ..... Click the link for more information. are very useful as tracers tracer, an identifiable substance used to follow the course of a physical, chemical, or biological process. In chemistry the ideal tracer has the same chemical properties as the molecule it replaces and undergoes the same reactions but can at all times be detectible ..... Click the link for more information. to study the mechanisms of complex organic reactions, since even minute amounts of these isotopes are easily detected by means of a Geiger counter or photographic film. For example, by feeding plants carbon dioxide that contains the radioisotope carbon-14 and by monitoring the carbon compounds through the plants' life cycle, the intermediate stages of the photosynthetic process can be determined. A method developed by W. F. Libby uses carbon-14 to date archaeological discoveries and other samples containing organic matter (see dating dating, the determination of the age of an object, of a natural phenomenon, or of a series of events. There are two basic types of dating methods, relative and absolute. ..... Click the link for more information. ). Radioactive substances have also been used to investigate the properties of artificially produced elements and to measure the rates of electron transfers. |

CHICAGO -- A key milestone in the imaging of Alzheimer's Disease (AD) has been reached through a close collaboration between radiochemists from the University of Pittsburgh and GE Healthcare. With more physicists, biologists, radiochemists and engineers than any other company in the world, we are developing in vitro diagnostic tests, combined with new targeted in vivo molecular imaging agents and sophisticated detection equipment, to provide fresh insight on health and disease management. |
