ASSESSMENT OF RADIOLOGICAL DOSES FOR PEOPLE LIVING IN KOREA FOLLOWING ACCIDENTAL RELEASES OF RADIONUCLIDES FROM NUCLEAR POWER PLANTS IN KOREA AND CHINA.

Accidentally released radionuclides are dispersed into the environment and cause human exposure through various pathways. Concerns about radiological impacts of a possible Nuclear power plant (NPP) accident in neighboring countries, especially in China, are increasing in Korea. Dose assessments for the hypothetical nuclear accidents in Korea (Hanbit and Wolsong NPPs) and China (Tianwan NPP) were conducted using the developed Korean code system. The results show that there is a possibility that a Tianwan NPP accident could have a slightly greater or similar impact on certain parts of Korea compared to accidents occurring at domestic NPPs, and could affect Korea within a few days of the accident. This research is expected to be used as basic material for preparing against nuclear accidents in neighboring countries.
