NAC459.347. Precautionary procedures: Use of process or other engineering controls; alternative controls; consideration of other safety factors.

     1. A licensee shall use, to the extent practicable, process or other engineering controls, including, without limitation, containment, decontamination and ventilation, to control the concentrations of radioactive material in the air.

     2. If it is not practicable to apply process or other engineering controls to control the concentrations of radioactive material in the air to levels below those that define an area of airborne radioactivity, the licensee shall, consistent with maintaining the total effective dose equivalent as low as is reasonably achievable, increase monitoring and limit intakes by one or more of the following:

     (a) Controlling access to the area;

     (b) Limiting exposure times;

     (c) Using respiratory protective devices; or

     (d) Using any other means available to control concentrations of radioactive material in the air.

     3. If the licensee performs an analysis of exposures to radiation to determine what exposure level is as low as is reasonably achievable and to determine whether respiratory protective devices should be used, the licensee may consider safety factors other than radiological safety factors, including, without limitation, consideration of the effect of respiratory protective devices on the industrial health and safety of workers.
