I second this comment. Tom Goff, a new member to this forum, did a 
similar study  a few years back while working at FPL. The object of 
the study was to determine the attenuation and transmission 
characteristics of different materials worn within the power plant 
when exposed to SDE. The study involved TLD measurements under 
various materials, such as PCs (protective clothing), respirator face 
mask, cotton gloves, rubber gloves, different thicknesses, whirl pak 
bags, etc. The study resulted in correction factors that could be 
applied to an individual's TLD in the event the dosimeter was worn 
either above or below the various materials. If the individual wore 
two rubber gloves for instance, there was no increased correction 
factor applied to the ring TLD, since there was in fact, no 
transmission of beta dose through the two gloves, and a highly 
conservative correction factor was not used, which was also 
needlessly applied to the gamma dose as well.

This was presented to the NRC and was well received.

So, I echo Ron's suggestion. Just do a simple test and document ...
