Title	Stuck Open Shutter
Event Description	The following information was received from the Arkansas Department of Health, Radiation Control (the Department) via email: On 12/18/2024, at 1530 CST, Exploratory Ventures LLC. notified the Department via phone that an IMS-5420-XX profile thickness gauge experienced a stuck open shutter. This gauge contains a 50.5 curie Cs-137 source, Eckert & Ziegler NuX.N27_A, serial number NR-1120-D-101-S, listed in the sealed source and device registry. An IMS technician arrived on-site at 1615 and was able to close the shutter at 1630. The gauge was moved from the in-line position to allow the technician to close the shutter; the technician opened the access panel on the gauge and placed an adjustable wrench on the pointer to manually close the shutter. As they started to turn the pointer, the spring of the shutter activated and closed the shutter. The technician closed the access panel then surveyed the area for radiation and found none. The gauge is currently locked-out and not in use. It will remain locked-out until an authorized service technician arrives to service the unit. The estimated date of service is pending. The investigation is ongoing and the report will proceed in accordance with SA-300. Arkansas Event Number: AR-2023-005
