On January 17, 2019, the NRC issued a Notice of Violation to Fleis & VandenBrink Engineering, Inc. for two Severity Level III violations for (1) detaching a sealed source from a source rod, without being specifically authorized to do so; and (2) handling of the unshielded cesium-137 source. Specifically, on July 16, 2018, the licensee's office technician detached a sealed source containing 8 millicuries of cesium-137 from the source rod of a Troxler 3400 series portable gauge that had been damaged at a temporary job site in Big Rapids, Michigan. Once the source was detached, the licensee's gauge user touched the unshielded source rod with their bare hands.
