Student's Guide
2. Be clean shaven in the area of the fit.
3. Use corrective lenses, if needed, that are
approved for respirators.
4. Be instructed to leave the work area when
experiencing respirator failure.
5. Be instructed to remove their respirators to
avoid life-threatening situations when exiting
an area after respirator failure.
B. Exposure to airborne radioactive materials
10 CFR 835 establishes dose limits which
includes internal dose from inhaling radioactive
material. Use of engineering and administrative
controls and proper use of personal protective
equipment results in most planned internal
doses being very low.
In cases of unplanned internal doses, potential
intakes of radioactive material are suspected
when personnel without respiratory protection
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.
