Event Description	The following information was provided by the Illinois Emergency Management Agency (The Agency) via phone and email: The Agency was contacted by the radiation safety officer (RSO) for Rush University Medical Center, on October 15, 2024, to report that a patient prescribed 66.67 mCi (479 Gy) of Y-90 Theraspheres on October 14, 2024, received only 20.14 mCi (144.7 Gy) of the prescribed dose. The patient has been notified and the RSO is still attempting to notify the referring physician who left on vacation immediately after the procedure. There was no reported adverse impact on the patient and the licensee is still discussing possible retreatment.

The underdose (69.8 percent deviation between the prescribed and administered dose) meets the criteria as a reportable incident under 32 Illinois administrative code 335.1080. Inspectors will perform a reactive inspection on October 17, 2024. A Medical Event may indicate potential problems in a medical facility's use of radioactive materials.
