Worker Exceeded Annual Dose Limit

On December 11, 2023, a pharmaceutical technician noted a pressure issue with a synthesis cell, which contained 11.29 GBq (305 mCi) of Fluorine-18. The pharmaceutical technician opened the synthesis cell and Fluorine-18 splashed onto their upper chest, neck, and underarm. The pharmaceutical technician could feel wetness after the incident, and decontamination efforts were initiated within 3 to 5 minutes. The skin exposure calculations, based on radiological survey results, indicated that the pharmaceutical technician received an estimated shallow dose equivalent of 0.902 Sv (90.2 rem). The dose to the employee exceeded the U.S. regulatory limit for the annual dose to the skin of the extremities of 0.5 Sv (50 rem). NRC Event Number (EN) 56923
