Small radiation doses: The unknown might hurt us
Roundtable Topic: Fukushima: What don't we know?
Radiation can't seem to stay out of the news. We worry about people over-exposed to CT scans, and people getting medically unnecessary x-rays. We worry about dirty bombs. Some even worry about whole-body airport scanners. Now, sadly, it's the Japanese nuclear accident: a few brave folks inside the reactor getting significant radiation exposures; and many worried people near the Fukushima Daiichi nuclear power plant, in the rest of Japan, and worldwide getting exceedingly small radiation doses. Just how worried should we be? What do we really know?
