XKCD: Radiation Doses

I know, getting "important" information from a webcomic site is probably not a good idea. But if I was going to get it from any webcomic, it would be XKCD.

Even the author agrees: "If you're basing radiation safety procedures on an internet PNG image and things go wrong, you have no one to blame but yourself."

It puts things in perspective.

And he gives sources.

And he's a physicist.

...but it's still a webcomic.

I'm just sayin.
