Scientists know that high levels of radiation pose a hazard to human health. What they don't know for certain is the health risk from exposure to low levels of radiation, such as from x-rays or some nuclear waste. In this hour, broadcasting from the annual meeting of the American Association for the Advancement of Science, we'll talk about how low doses of radiation affect biological systems and human health. Plus, how people perceive radiation risk, and involving the public in radiation policy decisions.
