The following is a summary of the information provided by the
Alabama Office of Radiation Control via email:
During routine bi-annual shutter checks, the licensee noted that their device had a malfunctioning shutter. The device's shutter failed in its normal open position. The licensee attempted to address the malfunction by spraying the shutter with lubricant, but the shutter's mechanism still presented a high resistance. The area has been barricaded off and procedures are in place to ensure that no one approaches the device or pipe until the malfunctioning device is replaced. The licensee plans to replace the source holder. Once the replacement is installed, the malfunctioning device will be put into safe state, removed from service, and securely stored until disposal. The estimated date for repair is January 31, 2026.
