Module 104 Internal Dose Control

Lesson Plan

Instructor's Notes

The internal exposure resulting from uranium entering the

body can be properly controlled by appropriate facility and

equipment design, contamination control procedures, and

protective clothing. A bioassay monitoring program to

determine the amount of uranium taken into the body is also

an integral part of internal exposure control.

Contamination Control Philosophy

Show OT-33

The control of contamination in the work place is a

significant part of the overall radiological

protection program at uranium facilities. Proper

contamination control will:

limit internal exposure by minimizing the

ingestion, inhalation, absorption, and injection of

uranium;

limit external dose from uranium and its

radioactive decay products; and

prevent the spread of radioactive materials into

uncontrolled areas.

Contamination Control Methods

Show OT-34

Because uranium is relatively less hazardous than

some other radioactive materials, such as

plutonium, some people can develop an overly

relaxed attitude to uranium; in effect saying, "It's
