The following was received from the State of
Kansas via email:
During Therasphere setup, a technician forgot to prime the syringe and inserted it into the vial of Y-90. She realized the syringe was not primed, but because the syringe cannot be removed, her attempt at priming it opened the vial inadvertently. It got tracked all over the room and to some extent all around the Interventional Radiology (IR) department. IR is now completely closed. She was put in a bunny suit immediately and sent to emergency to get deconned at the shower. There was no risk of internal contamination due to the rapidity of the decon after the incident. Highest contamination is at 90k on her scrubs. Most of the contamination was on her lead apron. The clothes are currently sequestered and lacking skin contamination, she was sent home. They are currently in the process of cleaning up and recovering to get IR back in business.
An investigator will be sent on Monday to gain first-hand knowledge of the incident. The RSO and ARSO were at a conference, arriving home last night, and were not present during the incident.
