Module 9: Radioactive Contamination Control
It may be transferred by casual contact, wiping,
brushing, or washing.
Air movement across removable contamination
could cause the contamination to become airborne.
Airborne contamination is contamination suspended
Types of Radioactive Contamination
See Student's Guide for Table
EO2 State sources of
Radiological work is required in areas and in
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,
The following are some sources of radioactive
Leaks or breaks in radioactive fluid systems.
Leaks or breaks in air-handling systems for
Airborne contamination depositing on surfaces.
Leaks or tears in radioactive material containers
such as barrels, plastic bags or boxes.
Another common cause of contamination is sloppy
work practices. These may lead to contamination of
tools, equipment, and workers. Examples include:
Opening radioactive systems without proper
