The posting/sign will indicate:

"CAUTION, AIRBORNE RADIOACTIVITY AREA"

A DAC is the radionuclide airborne concentration. Breathing an air concentration

of 1 DAC for 1 working year (2,000 hours) will result in committed dose

equivalent equal to an annual limit, i.e., 5 rem whole-body or 50 rem to any

organ or tissue.

Labeling of Radioactive Materials and Other Postings

1. "CAUTION, RADIOACTIVE MATERIAL"

Equipment, components, and other items that are radioactive, potentially

radioactive, or have been in contact with radioactive contamination or activation

sources.

2. "CAUTION, INTERNAL CONTAMINATION" or

"CAUTION, POTENTIAL INTERNAL CONTAMINATION"

Equipment, components, and other items with actual or potential internal

contamination.

3. "CAUTION, FIXED CONTAMINATION"

Components, equipment, or other items with fixed contamination.
