On September 22, 2008, a Notice of Violation was issued to the City of Kirksville, MO. an NRC licensee. This action is based on a Severity Level III violation of 10 CFR 30.34(i) involving the licensee's failure to maintain a minimum of two independent physical controls that formed tangible barriers to secure a portable gauge from unauthorized removal during a period when the portable gauge was not under the control and constant surveillance of the licensee. Specifically, on multiple occasions, the licensee stored a portable gauge in a laboratory using only a single barrier, the locked laboratory room door. In addition, on multiple occasions, the licensee transported a portable gauge, in its transport case, in the back of a closed-bed pickup truck with only a single barrier, the lock on the bed cover.
