AGREEMENT STATE REPORT - UNABLE TO RETRACT SOURCE IN INDUSTRIAL GAUGE
The following information was obtained from the Commonwealth of Virginia via email:
"On August 10, 2022, at 12:59 p.m. [EDT], the [Virginia] Office of Radiological Health Radioactive Materials Program (RMP) received an incident notification from the licensee. The source, 5 millicuries of Cs-137, could not be retracted behind the shutter during routine operations. The incident occurred on August 10, 2022 at about 12:00 p.m. (noon). The Radiation Safety Officer (RSO) stated that the insertion source detached from the retrieval cable during routine operations (due to high vibrations). The source was stuck in the dip tube (inside the insulation vat). They performed radiation surveys showing that no elevated levels were occurring outside of the insulation vat. Based on the notification, there was no personnel or public exposure due to this incident. The RSO contacted Berthold Technologies to come and perform the source retrieval. They are planning on arriving on August 11, 2022. This notification will be updated when additional information is obtained."

AGREEMENT STATE REPORT - LOST Y-90 MICROSPHERES
The following information was received from the Wisconsin Department of Health Services (the Department) via email:
"On August 31, 2022, the licensee notified the Department that they had lost control of licensed radioactive material. Per the licensee's report, on or about August 10, 2022, four sharps containers with yttrium-90 microsphere waste were inadvertently taken from the licensee's decay-in-storage room and placed in a locked room in the hospital's shipping department for disposal as biohazardous material. On August 15, 2022, the four sharps containers (approximately 60 millicuries of yttrium-90) were picked up by the hospital's biohazardous waste vendor, where they are assumed to have been autoclaved and disposed in a landfill. The licensee became aware of the loss on August 29, 2022. Based on the current activity of the sources (less than 1 millicurie) no attempt will be made to retrieve the material. No members of the public are expected to exceed public dose limits. A Department investigation is ongoing."
WI incident no.: WI220020
THIS MATERIAL EVENT CONTAINS A 'Less than Cat 3' LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
