Title	Agreement State Report - Shutter Mechanism Failure on a Fixed Gauge
Event Description	The following information was received from the State of Iowa via fax: On April 18, 2013, the licensee (3M Company - Ames) reported to the Iowa Department of Public Health that a shutter mechanism had failed to close on a fixed gauge at their Ames, Iowa facility. The device is a Thermo EGS Gauging, model ASC-185, serial number KA1527 containing a nominal activity (May 25, 2006) of 1250 millicuries Krypton-85. The licensee's RSO and trained maintenance staff proceeded to troubleshoot the cause of the failure to close. They identified that screws holding the shutter mechanism had become stripped and loose causing the source shutter to not operate properly. The gauge was removed and is now stored in a locked cabinet under the RSO's control. The RSO is currently pursuing the purchase of new screws so that the shutter mechanism can be repaired. Additional corrective actions include a more detailed inspection of the shutter screws during six month inspections. The sealed source (Krypton-85) is manufactured by Isotope Products Lab, S/N NER-588. IA Item Number: IA130003
