AGREEMENT STATE REPORT - DAMAGED GAUGE
The following report was received by the Utah Department of Environmental Quality, Division of Waste Management and Radiation Control via email:
"On April 15, 2025, a testing crew was conducting density tests using a gauge with a cesium-137 source on a road that was closed and blocked off. A truck drove down the road at a high speed and almost hit the gauge operator and hit the gauge. Everyone within a 30-foot radius was evacuated. The licensee is waiting for some assistance. No clean-up has been performed, and it is unknown whether the source within the gauge has been ruptured or not."

AGREEMENT STATE REPORT - MEDICAL EVENT
The following information was provided by the Illinois Emergency Management Agency (the Agency) via phone and email:
"The radiation safety officer for Northwestern Memorial Healthcare contacted the Agency on 4/17/2025 to report a medical underdose. Initial information indicated an underdosing of Y-90 TheraSpheres of 54 percent. The patient reportedly tolerated the procedure well and no further treatment is scheduled. The administering physician reported an issue with vasoconstriction of the target artery. The licensee confirmed that the patient and referring physician were notified. The licensee did not meet reporting requirements, which will be addressed during a reactive inspection to be conducted on 4/21/2025."
The intended activity was 17.03 mCi (630.11 MBq) and the administered activity was 7.84 mCi (290.08 MBq).
Illinois Reference Number: IL250016
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.
