IMPORTANT UPDATE: More than three years after this posting, the Health Physics Society, having been recaptured by radiation safety mafia, has removed the video series on the LNT from its web site and YouTube channel. The good news is that the series has been reposted on YouTube by copyright owner John Cardarelli. The radiation safety mafia does not want you to understand the LNT and its origins. Thank God for great Americans Ed Calabrese and John Cardarelli.
