| ENS 47958 | 24 May 2012 15:29:00 | During a routine bi-annual periodic inspection, a density gauge with a 4 milliCurie Cs-137 source was identified to have a stuck shutter. The gauge was an Ohmart Vega Model SHF1-A, S/N 0964C0. The instrument is permanently installed in an isolated tower area, and this event did not result in exposure to any personnel. The licensee plans on having the gauge repaired by the manufacturer. The licensee notified R3 (Bramnik). 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.
