The following information was provided by
Utah Department of Environmental Quality, Division of Waste Management [the Division] and Radiation Control, via email:
On January 31, 2023 at 1600 MST, the Intermountain Heart Institute, Cardiac Molecular Imaging Coordinator reported to the RSO [Radiation Safety Officer] that at 1445 MST a technologist, removing a Rb-82 (rubidium-82) generator from service, found liquid radioactive contamination in the bottom of the well chamber of the Infusion System. A syringe was used to remove the saline from the well of the Infusion System and the liquid was placed in the liquid radioactive liquid waste storage. Decontamination procedures were followed. The Infusion System well was wiped dry with paper towel(s). All radioactive waste was placed in approved radioactive waste storage. Wipe test(s) were performed.
This incident has no impact on patient treatment. All Quality Control procedures passed while the generator was in use which verifies that patient treatments were within all requirements.
The manufacturer was contacted for assistance and it is planned that the generator will be shipped back for investigation. We will follow the manufacturer's instructions for the shipment. A new generator has been placed in the Infusion System so that patient care can continue today.
The Division will investigate this matter and update the record upon completion of the investigation.
