SHTFriday: Ionizing Radiation for Dummies

Friday was a loss for me because I had a terrible headache, so I wrote this on Saturday -- and then promptly forgot to mirror it here. Now it's Sunday, and since posting this after my GunBlog VarietyCast post wouldn't make much sense, I'm just going to backdate this post, because I have that kind of power here.

Anyway, if my previous post about radioactivity didn't fully answer your question about Why Ionizing Radiation is Bad, this post ought to do that for you. Enjoy!
