Accidential Exposure of Industrial Radiography Worker
Print View Posted on: 26 December 2024
Event Date: 12 September 2023 Event Type: Radiation Source Event Location: Korea, Republic of, Yeosu INES Rating: 2 (Final)
On September 12, 2023, during industrial radiography, the control cable of the equipment ruptured, causing the radiation source(Ir-192, 1.75 TBq) to detach inside the guide tube. The worker was unable to notice the detachment of the radiation source in time due to the lack of proper radiation safety equipment and continued working. After completing the work, it was confirmed that all the taken film were overexposed, leading to the realization that the radiation source had detached. Although no clinically significant effects, such as blood abnormalities or skin tissue reactions, were observed, the radiation dose assessment indicated an effective dose of 116 mSv and a hand (skin) equivalent dose of 1967 mSv.

Exposure of Workers at a Facility using a Radiation Generating Device
Print View Posted on: 26 December 2024
Event Date: 15 July 2019 Event Type: Radiation Source Event Location: Korea, Republic of, Ansan INES Rating: 3 (Final)
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.
INES Rating: 3 – Serious incident (Final) as per 17 March 2020
