ANIMAL FACILITIES

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 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.
