|(a) When it is not practical to apply process or other engineering
controls to control the concentrations of radioactive material in air to values
below those that define an airborne radioactivity area, the licensee shall,
consistent with maintaining the total effective dose equivalent as low as
is reasonably achievable (ALARA), increase monitoring and limit intakes by
one or more of the following means:
(1) control of access;
(2) limitation of exposure times;
(3) use of respiratory protection equipment; or
(4) other controls.
(b) If the licensee performs an ALARA analysis to determine
whether or not respirators should be used, the licensee may consider safety
factors other than radiological factors. The licensee should also consider
the impact of respirator use on workers' industrial health and safety.
