Radioisotopes types
WebRadioisotopes in Consumer Products. (Updated January 2024) The function of many common consumer products is dependent on the use of small amounts of radioactive material. Smoke detectors, watches and clocks, cookware, and photocopiers, among others, all utilise the natural properties of radioisotopes in their design. WebRadioimmunoassays. Radioimmunoassay (RIA) is a competitive assay technique in which the reagent, the antibody (Ab), is used in a limited amount as compared with the amount of analyte antigen (Ag). To perform a RIA, it is essential to have a radioactively labeled antigen (Ag∗), which also is referred to as the tracer.
