Module 9: Radioactive Contamination Control
Instructor's Notes
a.
It may be transferred by casual contact, wiping,
brushing, or washing.
b.
Air movement across removable contamination
could cause the contamination to become airborne.
3.
Airborne contamination is contamination suspended
in air.

Radioactive Contamination
EO2 State sources of
Radiological work is required in areas and in
radioactive contamination.
systems that are contaminated by design (e.g.,
maintenance of valves in radioactive fluid systems).
Regardless of the precautions taken, radioactive
material will sometimes contaminate objects, areas,
and people.
1.
Sources
The following are some sources of radioactive
contamination.
a.
Leaks or breaks in radioactive fluid systems.
b.
Leaks or breaks in air-handling systems for
radioactive areas.
c.
Airborne contamination depositing on surfaces.
d.
Leaks or tears in radioactive material containers
such as barrels, plastic bags or boxes.
e.
Another common cause of contamination is sloppy
work practices. These may lead to contamination of
tools, equipment, and workers. Examples include:
1)
Opening radioactive systems without proper
controls.
