Versant Physics has a relatively new podcast called VersantCast: A Medical Physics & Radiation Safety Podcast where they interview experts in the health and medical physics / radiation safety field on a variety of topics. Their most recent episode was with Dr. Fellman, and he and their host Dr. Eric Ramsay discussed the Linear No-Threshold Model (LNT). They talk about what it is, scientific data that debates its efficacy, sustainable and nuclear energy, radiation hormesis, among other things.
Listen to Dr. Fellman discuss health physics, how he got into the field and how he turned from an anti-nuclear person to a pro-nuclear person.
