Requirements of Posted Contamination Areas cont'd

DOE-HDBK-1106-97

2. Requirements for working in posted contamination areas.

The RadCon Standard recommends that individuals allowed unescorted entry

into

Contamination Areas:

Avoid unnecessary contact with contaminated surfaces.

When possible wrap or sleeve materials and/or equipment brought into the

area.

Do not touch unexposed skin surfaces. This could result in skin

contamination.

Smoking, eating, chewing, drinking, and putting on makeup could result in

ingesting radioactive material; for this reason, the activities are not allowed in

Contamination Areas.

3. Requirements for exiting posted contamination areas.

RadCon Standard recommends that individuals allowed unescorted entry into

Contamination Areas:

a. Exit only at step-off pad.

A step-off pad provides a "barrier" between contaminated and other

areas to prevent or control the spread of contamination between areas.

Correct use of step-off pads is included in the practical factors

exercise.

If more than one step-off pad is used, the final step-off pad is "clean,"

outside the exit point, and adjacent to the boundary of the

Contamination Area.

b. Remove protective clothing carefully and slowly.

Loose contamination on the clothing can be dislodged causing a possible

spread of contamination or even potential inhalation if contamination

becomes airborne.
