Event Report Forms (ERFs) are filed to the IAEA. Sometimes there are multiple event reports, updating the rating, the event description. Here you only see the latest event report

ERF description: In July 2017, at a semiconductor manufacturing company, seven workers were exposed to radiation due to the abnormal use of an X-ray generator(100 kVp, 0.1 mA) for product defect inspection. The X-ray generator was a cabinet-type device with a shielding door interlock, but the workers manually disabled the interlock, allowing the shielding door to be opened while the X-rays continued to emit. While the X-rays were being emitted, the workers inserted their hands and upper bodies into the device to perform the work. Among the seven exposed workers, two workers developed radiation effects on their hands, including erythema, pain, and blisters. Radiation dose assessments conducted that while the effective dose for the seven workers did not exceed the annual dose limit, the skin equivalent dose exceeded the annual dose limit for all of them.
