Title	Fixed Nuclear Gauge Fell from Mounting Bracket Due to Rusted Through Mounting Bolts
Event Description	On the morning of 6/15/12, a fixed level monitoring gauge at the licensee's Merom Generating Station (coal fired facility), fell from its mounting bracket into a cable tray. The gauge, a Kay-Ray Model 7062P, S/N 9242Q, containing an estimated 50 mCi Cs-137 source (original activity - 100 mCi approx. 30 years ago) was not in service at the time, i.e., its shutter was closed, did not result in any personnel exposures. The licensee intends to have the instrument reinstalled using an outside contractor licensed to perform the work. The licensee contacted R3DO (Dickson). 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.
