Radioactivity in the Environment: What's the Risk?

Speaker 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.
