Radiation doses

A set of charts, fewer colors, more science terms, by a Senior Reactor Operator at the Reed Research Reactor, or this (larger version here and with lots of words here) by Randall Munroe based on the Reed one.



Munroe's may be republished "anywhere without any sort of restriction; I place it in the public domain. I just suggest that you make sure to include a clear translation of the disclaimer that the author is not an expert, and that anyone potentially affected by Fukushima should always defer to the directives of regional health authorities."
