| Event Description | The following information was received from the Minnesota Department of Health (MDH), Radioactive Materials Unit via email:
On Monday, July 7, 2025, at 1000 [CDT], the licensee discovered a gauge with a stuck shutter. The gauge is a Texas Nuclear fixed gauge with a 200 mCi Cs-137 source. Maintenance was planned on the apron feeder near the gauge. The maintenance group requested the electrical group close the shutter on this gauge. The electrical crew was unable to close the shutter after multiple attempts and decided to remove the gauge and place it in a container containing lead plates. The radiation safety officer (RSO) took readings 1 foot from the top and sides of the container. The highest reading was 0.3 mR/hr. The container was labeled as radioactive material and taped off with red tape. The RSO reached out to QAL-TEK to dispose of the unit. QAL-TEK stated they may be able to come out in less than two weeks. Minnesota Event Report ID: MN250004 |
