| Event Description | The following information was received from the Iowa Department of Public Health (IDPH) via email:
At 1515 CDT, July 7, 2022, an NDC Technologies, Model 302 fixed gauge with [approximately] 80 mCi of Kr-85 had a shutter stick open when the line was turned off. The shutter was first identified as stuck open around 1600 when the Radiation Safety Officer was conducting their entrance radiation survey. Radiation safety perimeter was established. The service provider was called and arrived the morning of July 8, 2022. They were able to close the shutter but unable to conduct cause analysis. The gauge will be shipped back to vendor to safely analyze for cause. The IDPH will decide on a reactive inspection based on the cause of stuck shutter identified by the vendor. Licensee aware of 30 day written notification requirement. IA incident no.: IA220004 |
