Pretty Images K-40

[FRAMEP@ORAU.GOV]

The USGS has color coded maps of the US (not individual states such as
New Jersey) showing K-40, U and Th concentrations as well as
exposure rate data available at 

http://sedwww.cr.usgs.gov:8080/radon/DDS-9.html

Who knows, maybe the data they provide for the NJ area might be
satisfactory.

Their counterparts in Australia have color coded images of K-40, U and
Th concentrations available at

http://www.agso.gov.au/environment/remsen/gen3d.html

The neat thing about these images are that the concentrations are
indicated in color on three dimensional images of the landscape.
