Security Requirements for Portable Gauges Containing Byproduct Material
The Nuclear Regulatory Commission (NRC) is amending its regulations governing the use of byproduct material in specifically licensed portable gauges. The final rule requires a portable gauge licensee to use a minimum of two independent physical controls that form tangible barriers to secure portable gauges from unauthorized removal whenever the portable gauges are not under the control and constant surveillance of the licensee. The primary intent of this rulemaking is to increase licensees' control of portable gauges to reduce the opportunity for unauthorized removal or theft.
