are exposed to airborne radioactive materials or
when respiratory protection has been
compromised. If unplanned intakes of
radioactive material are indicated that could
result in a committed effective dose equivalent of
100 mrem or more, the following actions should
be taken:
1. Identify personnel potentially exposed.
2. Determine the duration of potential exposure
to airborne radioactivity.
3. Have dose evaluated prior to permitting the
worker to return to radiological work.
