It will certainly be interesting to hear what Radsafers have to say,
but why not call Region IV (?) and ask them what their take on the
hypothetical is?

Regardless, please let us know what develops.

To: radsafe <radsafe at health.phys.iit.edu>

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
