1. (1) The licensee shall maintain the total effective dose equivalent ALARA by limiting intakes and increased monitoring if process or other engineering controls are not practical to control airborne radioactive materials concentration below those contained in the definition of airborne radioactivity area in Rule 0400-20-05-.32. The limitation of intakes and increased monitoring shall be by one or more of the following means:

   1. (a) Control of access;
   2. (b) Limitation of exposure times;
   3. (c) Use of respiratory protection equipment; or
   4. (d) Other mechanisms specifically approved by the Division.
2. (2) If the licensee performs an ALARA analysis to determine whether 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.
