I'd heard of the phenomenon, but I didn't appreciate why it happened or how long it could continue or how widespread it actually was.

The writer also greatly simplifies the concept of reactor physics.
Thanks. Yes, very interesting. I'd never heard of this before.
The world is so dang interesting, and the way we formally learn about it in school seems deliberately designed to make things as dry and dull as possible. Bill Bryson's "A Short Histroy of Almost Everything" does a tremendous job of making the "big stuff" fun, though I'm sure specialists will find it lacking.

It also solves everything, now we can just tell the anti-nukes: "Nuclear Reactions on Earth are natural!" You gotta love anything 'natural'!

Tigger, I think your characterization of the chart as "modified" is much more accurate than the Rothscum's label of "updated."

For those who want a recent (post Fukushima) version of the XKCD chart put out by the original authors and without Rothscum's editorializing (and scary red paint!!), it is below (and here).

"The European Committee on Radiation Risk has estimated that... the radiation exposure... has to be multiplied by a factor of 600".

Interesting. Who are the European Committee on Radiation Risk ? A public research body ? No, an anti-nuclear pressure group, with a Web site code by hand. Can we see the peer-reviewed science here, please ?
