Title	Stuck Open Shutter
Event Description	The following is a summary of information that was provided by the licensee via phone: On 6/10/2025 at approximately 1300 EDT, the licensee discovered that a Thermo Fisher density gauge containing 10 mCi of Cs-137 had a stuck open shutter while conducting routine checks on the gauge. Open is the normal position of the shutter. Surveys indicated the dose rate at 1 foot from the gauge is less than 1 mrem/hr. The gauge is on a pipe approximately 30 feet in the air, is not normally accessible, and poses no risk to personnel. The licensee has contacted a third party, Applied Health Physics, to assist them in decommissioning and disposing of the gauge.
