On May 15, 2013, the licensee reported that the shutter of one of its fixed gauges was not 'functioning per the design.' The problem was detected during the periodic shutter checks on May 15, 2013. The shutter could be closed but needed strong force to open it. The gauge is a Ronan Engineering Company, Model SA1-F37, Serial number M-2232. The gauge contains 50 mCi of Cs-137 as of the manufacturing date (remaining activity as of the incident date is 34.3 mCi).
Ronan Engineering Company was contacted and a schedule has been arranged for shutter repair.
A radiation survey was performed by the licensee and found to be within design parameters and regulatory limits. There are no public health or safety issues involved. The Virginia Radioactive Material Program will follow up with the licensee.
