Brookhaven maintains cross section info that is on-line accessible.

"NNDC" then "guest" I believe the target will have to be specified as
H-2 or H-2-G and the projectile as D or T . This might not work but
its worth a shot. 

Also, for what its worth, you can get decay data with a colored chart
of the nuclides at http://hpngp01.kaeri.re.kr/CoN/index.html

Soil concentrations in the south will vary a fair bit. Fallback
concentratons are 1 pC/g of the uranium and thorium series and 15
pCi/g for K-40. For published numbers you can look up the background
data in annual environmental reports for southern nuclear facilities.
If you send your mailing address I'll get you reported data for
Florida and Oak Ridge.
