Title	Failure of Ohmart "Density Profiler" Gauge
Event Description	The licensee's RSO reported that a "density profiler" gauge failed, and the 10 milliCurie Cs-137 source broke away from the gauge. The source is now at the bottom of a 10 foot deep well, which is inside a drum at the Alkalization Unit. The gauge is manufactured by OHMART, model MDTS and s/n 67524GK. The density profiler gauge has a source on the end of a tape, and the tape reels in and out of the instrument. When the tape broke, the Cs-137 source fell to the bottom of the well. No personnel exposure occurred. The RSO surveyed the area and found readings of 3 milliRem/hr at contact and 1.8 milliRem/hr at 1 foot. The licensee contacted the manufacturer who will be sending a technician out to repair the gauge.
