Event Date: 31 December 2016 Event Type: Radiation Source Event Location: Korea, Republic of, Yeosu INES Rating: 3 (Final)

In December 2016, it was reported to the regulatory authority that an industrial radiography worker’s personal dosimeter reading had exceeded the annual dose limit. An investigation revealed that the worker had been exposed to high levels of radiation on a night-field radiography work during November and December 2016. As a result, the worker developed a deterministic effect(pancytopenia). Additionally, three other workers at the same company were found to have exceeded the dose limit. Among the four workers, the highest effective dose was evaluated at a maximum of 1.19 Sv.

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.

In this study, partially supported by NIEHS, findings suggest that PM2.5 from wildfires is a greater risk factor for dementia than PM2.5 from other sources. This risk may be particularly pronounced among socially and economically disadvantaged groups. PM2.5 is a type of air pollutant composed of fine particulate matter less than 2.5 microns in diameter.
