- This correction is fundamentally true with respect to natural
- background sources in naturally eon-diluted form, but needs more
- precise quantification with regard to natural sources concentrated by
- technology and the assortment of artifical nucleotides bouncing around
- the environment in microscopic particulate form.
-
- For a start, due to their varying penetrating powers, there's orders of
- of magnitude difference between the effects of diffused exposure to
- alpha, beta, and gamma radiations. I don't ever want to be anywhere
- near a low intensity gamma source, but am not too concerned about a
- thousand specks of alpha-emitter taking up daily temporary residence on
- the *outside* of my epidermis. I _am_ concerned about the possibility
- of a sub-microgram bit of Chernobyl (or French, Chinese, .. atmospheric
- nuclear test) alpha/beta emitter taking up permanent residence in my
- lungs.
-
- (Failing to be quantitative about radioactivity seems to me to be on
- par with those "anti-nuclear" activists unclear on the difference
- between a vessel being nuclear-powered and being nuclear-armed.)
