On 24.09.2023, an employee of a company carried out a weld inspection in a radiation protection bunker using an X-ray device. After the measurement, the employee – who is also the radiation protection officer - went into the bunker to carry out further work. After completing the work inside the bunker, he realized that the X-ray device might still have been in operation during his stay. The immediate evaluation of the dosimeter provided a value of 71.5 mSv for September 2023. The dose measured with the dosimeter was above the annual limit of 20 mSv for occupationally exposed persons. The annual dose in 2023 before the event was 0.0 mSv. An expert inspection of the X-ray equipment determined that the equipment was technically in order. Therefore, it is assumed that it was not a malfunction of the device, but potentially a human error when operating the device. Further investigations are currently being carried out.
