No Abnormal Environmental Radiation Detected Around Hanul Nuclear Power Plant
Korea Hydro & Nuclear Power Hanul Nuclear Power Headquarters (Director Lee Seyong) held the '2023 Hanul Nuclear Power Headquarters Environmental Radiation Survey Briefing' for local residents on the 17th.
The Radiation Science Research Institute at Kyungpook National University (Director Professor Lee Sewook), the agency responsible for the environmental radiation survey, reported that the results of the environmental radiation survey and assessment conducted around Hanul Headquarters from January 1 to December 31, 2023, showed that "the environmental radiation levels are very good."
The Radiation Science Research Institute at Kyungpook National University analyzed a total of 764 terrestrial and marine samples, including 682 regular samples collected directly from the area around Hanul Headquarters and 82 samples of interest collected and submitted by residents.
The analysis results showed that artificial radionuclides such as cesium (137Cs) and strontium (90Sr) were detected in trace amounts, but these levels are consistent with those generally found in the environment in Korea and are unrelated to the operation of the nuclear power plant.
Additionally, very low concentrations of radioactive silver (110mAg) were detected in some marine organism samples, and trace amounts of tritium (3H) were found in some seawater samples. Assuming an adult consumes these annually, the annual dose is only about 0.00013% (radioactive silver) and 0.0372% (tritium) of the recommended annual dose limit of 1 millisievert (mSv), indicating a negligible impact on human health.
This year as well, Hanul Nuclear Power Headquarters and the Radiation Science Research Institute at Kyungpook National University plan to continue monitoring the environmental impact of nuclear power plant operations through ongoing environmental radiation surveys in the surrounding area.
