Dose Potentials
Animals that have had radionuclides administered to them can present a hazard both to the
individuals working with them and to the success of the experiment as well. When using
radionuclides in animals, one must be sure that the cages are well labeled, away from much foot
traffic, and properly maintained to minimize the hazards arising from radionuclide use. Hazards
that are likely to be encountered when using radionuclides in animals are listed below:
3.1
External personnel exposure resulting from gamma-emitting radionuclides that have been
used in an animal.
3.2
Internal radiation exposure resulting from accidental ingestion of radionuclides.
3.3
Cross contamination of radionuclides from one radiological experiment to another.
3.4
Room contamination that can result in the spread of radionuclides to a non-radioactive use
area.
