Title	Medical Event
Event Description	The following information was provided by the licensee's radiation safety officer (RSO) via phone: During an audit performed on 04/16/2025, it was discovered, that on 01/24/2025, a patient had received a dose to the liver that was greater than 20 percent of the prescribed dose. The prescribed activity was 24.3 mCi of Y-90 microsphere, an equivalent dose of 21.95 grays to the liver. The spreadsheet containing the activity verification incorrectly listed the activity as 26.9 mCi. The actual activity administered to the patient was 29.8 mCi, an equivalent dose of 26.9 grays, which is 22.6 percent (4.95 grays) greater than the prescribed dose to the liver. The RSO intends to contact the patient and doctor. 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.
