[ RadSafe ] FIDLER Scan MDC Values for Natural Uranium and Ra-226

[Dan Hoffman]

Hello Radsafers.  I am seeking information regarding the above subject.  I
am aware of the documentation in the December 2006 draft MARSAME document
for U-nat and Th-nat.  However, if anyone out there has worked up
calculations for their site-specific conditions that they would be willing
to share I would very interested in obtaining a copy of the documentation.
The particular site at which I am involved has a very low U-nat cleanup goal
of 17 pCi/g.  That is the primary rationale for use of the FIDLER vs the
more commonly used 2x2 NaI detectors.  The Ra-226 cleanup goal is the
'standard' 5 pCi/g criterion.

 

Thanks in advance for any insight you can provide.

 

Regards,
