Event Date: 03 December 2015 Event Type: Radiation Source Event Location: Korea, Republic of, Pyungtaek INES Rating: 3 (Final)

On December 3, 2015, an industrial radiography worker repeatedly conducted NDT without realizing that a sealed radioactive source(Ir-192, 1.1 TBq) had not been properly retracted and remained at the end of the guide tube. On December 8, the worker began feeling symptoms such as pain, redness, and blisters on both hands. Although the worker received treatment at a common hospital, no further actions were taken at that time. On January 27, 2016, the incident was reported to the regulatory authority, and the worker received treatment at a specialized hospital on radiation hazard. The equivalent dose to the worker’s hands was estimated to be approximately 30 Sv.

Event Date: 20 April 2015 Event Type: Radiation Source Event Location: Korea, Republic of, Busan INES Rating: 2 (Final)

On April 20, 2015, two workers were conducting a industrial radiography for Non-Destructive Test on the welds of a large steel product. During the process, the guide tube of the irradiator was not properly connected, causing the radiation source (Co-60, 1.85 TBq) to be withdrawn but not retrieved. One of the workers entered the radiographic testing room to retrieve the radiation source but accidentally stepped on the source without realizing its location, resulting in radiation exposure. On May 6, 2015, erythema was observed on the sole of his right foot, leading to the recognition of excessive radiation exposure. The doses were assessed as an effective dose of 0.9 mSv and a foot equivalent dose of 2.5 Sv.

On June 26, 2014, during the setup and operation of testing equipment for industrial radiography, a radiation exposure incident occurred. The support structure of the equipment fell onto the guide tube, causing it to deform and disabling the retrieval of the radiation source(Co-60, 2.1 TBq). While attempting to repair the damaged portion of the guide tube by hand, the worker was exposed to radiation. The personal dosimeter reading indicated an effective dose of 117.1 mSv. Radiation burns were observed on the worker’s hand, and the hand equivalent dose was estimated to be between 10 and 25.8 Sv.
