On November 23, 2015, the NRC issued a Notice of Violation to CTI and Associates, Inc., for a Severity Level III violation of both 10 CFR 20.1801 and 10 CFR 30.34(i). The violation involved the failure to secure licensed material in a portable gauge from unauthorized removal or access, with a minimum of two independent physical controls that form tangible barriers, while the gauge was stored in a controlled or unrestricted area and not under the control and constant surveillance of the licensee. Specifically, the licensee left an unattended gauge inside an unlocked shipping container that was accessible to the public.
