Event Description	The following information was received from the Massachusetts Radiation Control Program (the Agency) via email: On 3/14/2024 at 1225 EDT, a MDS Nordion, Inc. GammaMed Plus iX high dose rate (HDR) remote afterloader device malfunctioned, leaving the source in an unshielded position. Since the quality assurance/quality control (QA/QC) checks are performed in a shielded room, no individuals received any excess dose due to this device failure.

This repair work is ongoing at the time of this report. The Agency will follow up with UMass Healthcare Radiation Safety Officer (RSO) to determine event cause and corrective actions. The Agency considers this event open. The Agency will follow up with a special inspection of the licensee. Device Information: MDS Nordion, Inc.
