I’m encountering a lot of people who are understandably concerned about radiation leakage from the damaged Fukushima plant in Japan. But very few of them seem to know the extent to which exposure to radiation is a fact of life on Earth. Did you know, for instance, that you’ll be exposed to more radiation by eating a banana than by living within 50 miles of a nuclear power plant for a year?
Randall Munroe, who pens the hilariously geeky webcomic, xkcd, has teamed up with a friend at the Reed Research Reactor to create a visual aid for understanding radiation exposure levels. As Munroe cautions, the situation at Fukushima seems to be changing by the hour, but this should at least help put things in perspective.
