| Title | |
| Event Description | At 11:30 AM December 19, 2011, the licensee's radiation safety officer provided a 24-hour telephone report notification of a shutter failure on a gauge. The gauge involved was an Ohmart SH-100, serial number 70230, containing 10 mCi of CS-137, with an assay date of Aug 1981. The shutter mechanism is a lead block screwed to a sliding aluminum plate. The licensee was removing the gauge from its mounting to replace it with a different new gauge as permitted by their license. When the licensee removed the gauge from its mounting, the lead block separated from the aluminum plate. The licensee replaced the lead shielding and secured it in place. The licensee secured the gauge from unauthorized access and will return it to the manufacturer for disposal with other gauges they are replacing. The licensee states that no personnel received radiation doses during this event.
