 You can't blend, but you can sort and segregate. This often results in largely the same outcome.

Subject: [ RadSafe ] Soil Blending

I have been working with a client who has somehow latched onto the idea they 
could blend soil to lower the overall radionuclide concentations in soil to make 
the soil acceptable for disposal on the site of origin. In my opinion the only 
way that could be done would be to submit to the NRC or the agreement state an 
exemption request to do that type of operation. My client has asked, and as a 
dutiful consultant I am acceding (reluctantly) to their wishes, that I find out 
if anyone has ever been allowed to do a purposeful blending operation with the 
objective of on-site soil disposal. So here are my two questions:

1. Have you ever heard of soil blending being allowed on a U.S. site for the 
purpose of lowering the concentrations to below the DCGL and thus meeting free 
release criteria for the site.

2. If the answer to 1 above is yes did they apply for an exemption from the NRC 
or agreement state or did they simply do the work as part of an approved 
Decommissioning Plan?

If you wish to keep any info on the QT just email me directly or call but keep 
in mind I am on the west coast so early moring risers on the east coast  try not 
to call at 7:00 your time.

Thanks for any info in advance
