| ENS 56465 | 3 March 2023 04:00:00 | Agreement State | Stuck Open Shutter (Repaired) | The following information was provided by the Ohio Department of Health via email: On 3/3/23, the general licensee discovered a generally licensed device (used for package content measuring) with a failing source shutter, or the 'open-close' mechanism, was likely failing in the open position during scheduled internal routine inspection. The receiver portion of the device demonstrated radiation readings were present in the bridge opening when the shutter should have be closed and reading no presence. The manufacturer was contacted and the device was taken out of service per the manufacturer's advice regarding the regulations. On 3/21/23, the manufacturer arrived on site, repaired the shutter device, and conducted a survey of the device to ensure the shutter was closing properly after repairing. The survey after the repairs, showed that even with the shutter open, outside the direct beam, annual radiation levels would be less than 100 mrem per year.
