The nuclear disaster is still going on in Japan, and radiation has been detected around the Pacific rim. The government reassures us, rightly so, that levels are not harmful in any way. I just can’t help thinking that a little more information, and a little more, and a little more, (ad infinitum) will always help.

This chart of how much ionizing radiation a person can absorb may help in how you think about the difference between Chernobyl and Fukushima.
