Re:Breast Cancer...Some Ideas

Dear Ted de Castro:

     Hmmmmm.......

     I don't think surface carbon is what is important here.  Clearly the 
Cosmic
rays have some rather strong penetrating ability into the breast.  The amount 
of
penetration (i.e. the depth), in-scattering and out-scattering of 
neutrons/protons/
hadrons, the creation of secondary particles (i.e. particle multiplicity, 
etc.) are 
what is important.  To some degree, the shape, size and composition of
each breast will control the degree of C-14 production (or production of
other radioisotopes).

     Extremely minute quantities possibly exist for single reactions.  Such
reactions, when summed over 5 - 10 years, may be significant.  I don't 
know,....
I haven't done the relevant calculations yet.

     Thanks for your comments.
