Saturday Science Exploration Series: Radioactivity in the Environment: What's the Risk?


Location: Jordan Hall, College of Science, Room 101

Amy Hixon, Assistant Professor of Civil and Environmental Engineering

Uranium and thorium are naturally-occurring radioactive elements that are widely distributed among rocks and minerals. However, most actinide elements are present in the environment as a result of nuclear weapons production and testing, nuclear fuel disposition, and nuclear fuel cycle accidents (e.g., Chermobyl, Fukushima Daiichi). These actinide elements pose a long-term environmental concern due to their toxicity and long half-lives. In this talk, Professor Hixon will discuss what the Environmental Radiochemistry group is doing to understand and predict actinide mobility in the environment.
