Oh!  Thank you so much for that clarification.  I did not mean to spread
confusion, so I am glad you posted this to the list.  And  my apologies if I
mislead anyone.

     The carbon-14 model used in RESRAD is designed for soil
contamination. 
     The sentence you quoted refers to carbon-14 models found in the 
     literature as cited in that sentence (Page 316, last sentence, RESRAD 
     Manual). Please contact me directly if you have further questions on 
     carbon-14 modeling in RESRAD.

I have been using the RESRAD model to look at various isotopes in soil.  I 
am currently trying to look at carbon 14.  The model assumes that this is 
an extremely mobile isotope (in the same category as tritium).  The
RESRAD manual says "the modeling for carbon-14 has evolved from 
analyses of atmospheric sources and is not appropriate for ground 
contamination sources."  Does anyone know of a model that is 
appropriate for ground sources?  Are there any good discussions about 
carbon 14 in soil?
