Re: Breast Cancer...Some Ideas
What I meant by "surface carbon" was to exclude stuff DEEP underground.
I've worked with high energy accelerators most of my career - I am aware
of the reactions of high energy particles.
The carbon in almost anything of more than minimal mass - say trees and
other body parts would see the same reactions in the same amount.
With a uniform irradiation for a effect to be so singled out there must
be something of particular "resonance" - like JUST the right size - to a
very unique extent.
I'm not saying "NO WAY" - I'm saying due to the uniformity of
irradiation
I very much doubt it. And - I don't see any factors regarding the human
breast as particularly "resonant" to those effects.
True - amounts may accumulate - but they accumulated EVERYWHERE that
cosmic rays are bombarding.
IF by some chance this WERE to be true - I'm sure the shielding would be
VERY uncomfortable!
