Title	Level Gauge Shutter Failure
Event Description	The shutter for an Ohmart SHRM-B strip source containing 12 millicuries of CS-137 failed in the open position. The source is used as a level instrument with the shutter normally open for this application. For the past two weeks the licensee attempted to close the shutter without success. On April 6, 2009 at 0830 the shutter pin broke while employees were attempting to once again close the shutter. There were no personnel radiation exposures during this event. The licensee is devising a method to shield the source and remove it for shipment to a repair facility.
