Meet EPA Scientist Sang Don Lee, PhD

The U.S. EPA's Office of Research and Development (ORD) hosts the Emergency Response Research Webinar Series, a public webinar series featuring presentations to share EPA research to help inform decisions for state and local governments, tribes, and others.

March 11, 2021, marked the 10-year anniversary of the accident at the Fukushima Daiichi Nuclear Power Plant in Japan which was caused by an initial earthquake and subsequent tsunami. This was the most significant accident at a nuclear power plant since the Chernobyl disaster in 1986. The Fukushima Daiichi Nuclear Power Plant accident resulted in radioactive contamination over a wide area and environmental remediation was necessary to protect public health. The scale of contamination was unprecedented in Japan and their efforts to effectively remediate the contaminated environment have identified many valuable lessons.

This webinar covers 1) how EPA responded to this accident to protect our nation and what actions EPA has undertaken to improve and strengthen its response capability since then, and 2) how Japan conducted remediation of the off-site contaminated environment focusing on their preparation, implementation, and verification of the work. Throughout Japan’s remediation efforts, several challenges have been identified and this presentation will share experiences and lessons that will greatly benefit decision makers and responders who have to prepare for wide area environmental remediation to respond to and recover from radiological contamination events.
