During an inventory, a hotel manager discovered two exit signs were lost, each containing 7.62 Ci of tritium.
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.

EN Revision Text: STUCK SHUTTER
The following information was received from the licensee via email:
"At 0745 CDT, a Systems employee was in #14BF stock house performing lockout tagout procedures in preparation for an outage. As the employee was attempting to close the shutter on the north Berthold gauge, the handle broke leaving the shutter stuck in the open position. No personnel were exposed to the source. Under normal operating conditions the shutter remains open and doesn't pose an immediate hazard while following established procedures.
"Initial Corrective Actions:
- Performed a survey in the work area. No readings above background.
- Posted signage indicating that the shutter is inoperable, stuck in the open position, and informing employees not to enter.
- Contact manufacturer representative (Radiametrics) to schedule assessment and repairs."
The Berthold gauge contas a 300 milliCurie Am-241/Be source.
