AGREEMENT STATE REPORT - SHUTTER ON GAUGE INOPERATIVE

"On March 21, 2009, at 1050 AM, the Agency [Texas Department of Health] received a report from the licensee that while performing the biannual test on a Ronan Engineering nuclear gauge, model # SA-1, containing an original activity of 100 millicuries (calculated current activity of 75 millicuries) of Cesium (Cs) - 137, the shutter failed to close. The gauge is installed on the side of a vessel approximately 50 feet above ground and is used for level detection. A dose rate measurement taken at the gauge indicated 0.03 millirem per hour, and poses no risk of radiation exposure to their workers. The manufacturer has been contacted to provide corrective maintenance on the shutter."
