CBRN event in Korea, Republic of on Tue 19th November 2024

In November 2024, a worker was exposed to radiation during the inspection of an X-ray device used for foreign object detection in manufactured products at a facility that produces and sells such devices. The worker was conducting performance improvement work on the device (80kV, 1.25mA) and, without turning off the power, inserted his hands into the machine to disassemble and reassemble the collimator, while X-rays were being continuously emitted.
Since the device was still in the production phase, radiation warning lamp had not yet been properly installed. The worker continued the task without being aware that radiation was being emitted.
Subsequently, localized radiation effects such as erythema and pain appeared on the worker's hand. According to the dose assessment, the equivalent dose to the skin on the worker’s hand was estimated to exceed 2,000 mSv, surpassing the annual dose limit.
