AGREEMENT STATE REPORT - RADIOGRAPHY SOURCE DISCONNECT

The following was received from the Illinois Emergency Management Agency (the Agency) via email:

"The Agency was contacted at 0830 CDT on 5/3/22 to advise that a radiography crew had a 55 Ci Ir-192 source disconnect from the drive cable while working at a site in Bradley, Illinois over the evening. The crew contacted their RSO and the source was successfully retrieved and placed into a shielded position. As the work was done after hours, there are reportedly no concerns over public exposures. Three MISTRAS staff recorded maximum exposures of 65 mrem on their [direct reading dosimeters] DRDs from the operation and have overnighted dosimetry for processing."
