" 'Or we could say that about 62.5 pCi/kg = the 10CFR50 human dose

Clearly all the other assumptions of the model make this very conservative, but it's a starting point.
I hope this is in the ball field of what you were looking for.... We have a lot more work to do with the lab, including sending some blanks, splits, spikes, from OUR chem lab and working out an INTERLAB program form someone. Adding some degree of Reg Guide 4.15 to GW is in our corrective action program due in March, but of course we are working on it now.
