| Title | Agreement State - Source Failed to Retract |
| Event Description | The following information was provided by the Illinois Emergency Management Agency (the Agency) via email and phone:
The Agency was contacted on 12/2/24 by radiation oncology staff at Advocate Christ Hospital to advise a 4.3 Ci Ir-192 source for a high dose rate afterloader (HDR) was stuck in the exposed position. The source was extended for daily quality assurance checks and is within a shielded vault. There were no staff or patient exposures. The manufacturer has been contacted to dispatch a service technician to the site and is expected 12/3/24. Agency staff conducted a reactive inspection on 12/2/24 to verify public exposure rates were within limits, verify adequate room security could be maintained, and determine the resources made available by the licensee to prevent any radiation exposures. After investigation, inspectors found the licensee had effectively restricted access by installing a secondary key-pad controlled door outside the vault door. Appropriate signage had been installed and survey readings in all areas were confirmed to be below public exposure limits (max 40 microrem per hour). The fault appears to be electrical and updates will be provided once obtained from Varian staff. Equipment information: Device name: Remote afterloader HDR Model number: GammaMed Plus iX Serial number: H641313 Manufacturer: Varian Illinois item number: IL240030 |
