Title	Agreement State - Source Stuck in Unshielded Position
Event Description	The following information was provided by the Texas Department of State Health Services (the Department) via email: On December 7, 2023, the Department was notified by a Texas licensee's radiation safety officer (RSO) that while testing an MDS Nordion, Model Eldorado 8, teletherapy unit, the 1,817 curie cobalt-60 source became stuck in the unshielded position. The RSO stated that the room was isolated and dose rates taken outside the room did not create an exposure risk to any individual. The RSO stated that a service contractor would likely repair the unit on December 9, 2023. Access to the room was posted to prevent inadvertent entry into the room. An update will be provided when the source is returned to the shielded position and then further information will be provided per SA-300. Texas Incident Number: I-10070 NMED Number: TX230056 * * UPDATE ON 12/9/23 AT 1137 EST FROM RANDELL REDD TO KAREN COTTON * * * On December 9, 2023, the Department was notified that the cobalt-60 source had been returned to the shielded position by the licensed servicing company. The technician who returned the source received around 0.3 millirem. The source activity is likely around 1,000 curies and not 1,817 curies, as originally reported. The Department will wait for the licensee and service company reports for information regarding the cause of the incident and report this to NMED per SA-300. Notified R4DO (Dixon) and NMSS Events Notification via email.
