Instructor's Notes

1.0

Objective

Describe the exposure potentials when handling animals that

contain radionuclides during experiments.

2.0

Outline

Exposure potentials.

Methods of minimizing external exposures.

Methods of minimizing internal exposures.

Methods of minimizing cross contamination.

Room contamination problems.

3.0 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

gammaemitting 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.
