DHS 157.87(7)(f)3.3. The effective dose to an individual for a single inadvertent exposure to the primary beam shall not exceed one mSv (100 mrem). The reliability of the procedure used to assure that there are no occupants of a vehicle to be scanned shall be commensurate with the potential severity of an inadvertent exposure. If the one mSv (100 mrem) limit cannot be assured, a pre-screening with a mode or system which may meet the limits in pars. (c) to (e) shall be used to verify there are no occupants in the vehicle being examined. DHS 157.87(8)(8) Application for exemptions.
