Title	Agreement State Report - Source Shutter Not Fully Closing
Event Description	The following information was received by e-mail: Licensee notified DRH [Mississippi Department of Radiological Health] about a Ronan X92 Continuous Level Gauge, Serial No. 9479GG with source Holder Model SA1-F37. Licensee suspects the source shutter may not be closing 100% due to elevated readings of 7 mR/hr with the shutter in the closed position. * * RETRACTION FROM JASON MOAK TO PETE SNYDER ON 6/26/12 AT 1558 EDT * * * This report is retracted based on the fact that the gauge "did not fail to function as designed. No maintenance was performed on the gauge. The service representative did not find a problem with the gauge shutter or radiation fields. Notified R4DO (Clark), FSME (e-mail). Mississippi Incident Number: MS-12002 THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf Note: This device is assigned an IAEA Category 3 value based on the actual radioactivity of the source, not on the device type.
