Predictors of public risk perception of Fukushima Daiichi nuclear accident's treated radioactive wastewater release: Study on South Korean population

초록

The International Atomic Energy Agency (IAEA) declared in early July 2023 that the release of treated radioactive wastewater from the Fukushima Daiichi Nuclear Power Plant (FDNPP) would have negligible effects on the water ecosystem and human lives, and soon after the Japanese government started the release on August 24, 2023. However, international concern regarding its harmful impacts continues, especially among the public. This study aimed to assess the factors influencing the risk perception of South Korean adults regarding Japan's treated water release through an online survey of 987 adults aged 20-59. The results showed that risk perception was significantly higher in females and associated with subjective knowledge, involuntary exposure, and low perceived controllability. Furthermore, trust in both the South Korean and Japanese governments as information sources, as well as trust in the South Korean government's evidence-based policy implementation were significantly associated with risk perception. Addressing public anxiety about treated wastewater release requires alleviating feelings of anxiety, two-way communication with stakeholders, empowering individuals with reliable information and addressing their concerns. Collaborative efforts between South Korea and Japan, involving local leaders and experts, can build trust and promote effective risk communication, mitigating fears of involuntary exposure and historical distrust.
