When you are showered by gamma/cosmic rays, or high energy particles, does it matter where they come from?

My point is, cosmic rays or space itself cannot be "radioactive". Radioactivity is a property of ordinary matter.

But yeah, I'm being needlessly pedantic. Thanks for the submission, I did enjoy the "article". And thanks for linking directly to the source, by the way -- that's something that rarely happens on /. these days.
