The following information was provided by the Illinois Emergency Management Agency via phone and email:
"On 6/25/2025, the associate radiation safety officer at Northwestern Memorial Healthcare (IL-01037-02) called to advise that following a successful Sir Spheres therapy procedure at Central DuPage Hospital, the nuclear medicine technologist dropped the residual dose vial containing 72 mCi of Y-90 Sir Spheres on the floor within the nuclear medicine hot lab (restricted area). Nuclear medicine personnel followed emergency procedures and promptly notified radiation safety staff. Contamination of personnel was limited to clothing and booties which were immediately removed and placed in storage for decay. Subsequent personnel surveys were conducted and confirmed contamination was limited to clothing and booties with no contamination to the skin. The licensee met reporting requirements of 32 Ill. Adm.
