Radiation Exposure Explained: Putting Japan in Context
This is a very good, easy-to-understand discussion of how much radiation we are typically exposed to and what the regulatory limits are, to help put into context the radiation levels being reported in Japan and even now in the US.

Justin, a couple of graphic designers/visual artists have created really exceptional illustrations of radiation exposure levels and ranges to better communicate to a lay audience an understanding of radiation threat and this related jargon.
You can see one Radiation Dose Chart here: http://xkcd.com/radiation/ and at this link is another really finely designed Radiation Dosage Chart: http://www.informationisbeautiful.net/visualizations/radiation-dosage-chart/
That last site has other fantastic examples of information presented through good design.
