One of the easiest ways is to use the NRC VARSKIN2
computer code.  I have also seen a good approach
that was in the May/June 1988 RPM, that was prepared
by John Flood, who was at the time with TVA.  The article
was entitled "Practical Methods for Determining Dose From
Radioactive Skin Contamination."  This article
offered means to use pancake probes in performing the
dose evaluations.  The isotope specific DCFs used in
this approach were taken from the previous version of
VARSKIN, and probably could be updated using the newer
version.  How far you take this depends on how cookbook
you want the dose evaluation to be, and how many
assumptions you can reasonably make about your
waste stream.

Best regards.
