| radioactive tracers | Radioactive substances added in minute amounts to the reacting elements or compounds in a chemical process and traced through the process by appropriate detection methods, e.g., geiger counter. Compounds containing tracers are often said to be tagged or labelled. (12 Dec 1998) |

| radioactive waste | <radiobiology> Equipment and materials from nuclear operations which are radioactive and for which there is no further anticipated use. Wastes are generally classified as high-level (having radioactivity concentrations of hundreds to thousands of curies per gallon or cubic foot), low-level (in the range of 1 microcurie per gallon or cubic foot), or intermediate (between high and low). See: curie. (09 Oct 1997) |
| radioactive isotope |
A form of a molecule that emits radiation. There are three principal type of isotope emitters: alpha, beta, and gamma. Isotopes can be used as diagnostic agents in nuclear medicine. Such agents are chosen because they have an affinity for certain organs or tissues. One can use instruments to detect these isotopes. Brain, bone, liver, and spleen scans are examples of use of isotopes for diagnosis of abnormalities of those organs. Certain radioactive isotopes can damage cancer cells. ...

| radioactive tracer |
A known amount of a radioactive substance added to an experiment usually to trace (with a geiger counter or similar equipment) the movement of the non-radioactive component of that element through the experiment. Such tracers have important uses in biology and chemistry.
