Minn. R. agency 144, ch. 4731, STANDARDS FOR PROTECTION AGAINST RADIATION, pt. 4731.2240 - CONTROLLING CONCENTRATION OF RADIOACTIVE MATERIAL IN AIR
Subpart 1.
Process or other engineering
controls.
A licensee must use, to the extent practical, process or other engineering controls, such as containment, decontamination, or ventilation, to control the concentrations of radioactive material in air.
Subp. 2.
Other
controls.
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, a licensee must, consistent with maintaining the total
effective dose equivalent 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 a 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 must also
consider the impact of respirator use on workers' industrial health and
safety.
