Radiation Superstition

By Robert Hargraves Nearly a million people each year die of breathing particulates from burning coal; the climate temperature may increase 2°C this century; more than a billion people have no electricity. Yet within our reach is a solution to these global crises of increasing air pollution deaths, climate change, and the growing populations of…

Measuring natural gamma radiation that human bodies have evolved to handle

Communicating complex subjects is often easier in person or on video. As one of my visually oriented friends likes to say, if a picture is worth a thousand words, a good quality video can be worth 30,000 words per second. Here is a clear, short video that shows how natural gamma radiation surrounds us all…

Atomic Show #197 – Radium, educational museums and Voices for Vermont Yankee

Fear of radiation has ruined far more lives than exposure to radiation

Ted Rockwell, one of my favorite nuclear energy professionals, recently shared the following comment on an email list that was discussing a recent report about the National Academy of Sciences effort to learn lessons from Fukushima. This fact should be stated loud and clear, right up front: In every “nuclear disaster”. radiation injured few if…
