Event Date: 11 December 2023 Event Type: Other Event Location: United States of America, Romeoville, Illinois/ SOFIE INES Rating: 2 (Final)

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

Event Date: 09 March 2023 Event Type: Radiation Source Event Location: Germany, Lower Saxony / Company for Material Testing INES Rating: 3 (Final)

On 09.03.2023, an employee of a company carried out a weld inspection using an X-ray device. To align a workpiece to be tested, the worker left his workstation disregarding the radiation protection warning measures, which consist of a barrier rope, a flashing warning light and the warning signal of a radiation protection dosimeter which measured the local dose rate. The workers head came into the beam of the X-ray device in operation for a duration of about 2 minutes. An effective whole body dose, an equivalent dose for the lens, and an equivalent dose for the skin were estimated based on a reconstruction of the likely scenario. The effective whole body dose was set to 230 mSv and the equivalent dose for the lens of the eye was set to 546 mSv by the authority. An expert inspection of the X-ray device determined that the equipment was technically in order. The cause
