UNAUTHORIZED USE OF A RESTRICTED RADIATION ROOM AS A TOUCHDOWN SPACE
On July 14, 2020, at approximately 1115 MDT, the Radiation Safety Officer was notified that a restricted radiation room was used intermittently for 30-45 minute periods as a touchdown space for Billings Clinic's Internal Medicine residents. The room had not been decommissioned.
The restricted radiation room being used was the Billings Clinic Hospital I-131 Inpatient Therapy Room (room 3501; general inpatient medical floor). This room was last used for [a 153 mCi I-131 Sodium Iodine] radiation treatment on June 21, 2017. Beginning June 4, 2020, the room began being used as a touchdown space for Internal Medicine residents. Surveys were performed on July 14, 2020 using survey meters. Wipes for removable contamination were performed on a table, two computers, phone, and the floor around the area where staff were working. All items had activity levels indistinguishable from background readings. The items were removed from the room. The room has been secured with a new lock and radiation warning signs have been reposted. The radiation signs had been removed at an unknown time between June 4, 2020 and July 14, 2020.
