I just received a link to a fascinating podcast from the World Nuclear Association about the risks associated with attempting to protect the public from low doses of radiation. It was posted almost a month ago on October 14, 2014. I apologize for initially missing this important recording and failing to bring it to your attention.
Here is the quoted blurb about the discussion:
Roger Coates, IRPA; Malcolm Grimston, Imperial College Centre for Energy Policy and Technology; Willie Harris, Exelon Nuclear; Wolfgang Weiss, UNSCEAR debate key issues for radiological protection. Moderator: Jack Valentin
Thank you @arclight!
