Sargoytchev mentions the Demron technology for high energy gamma reduction. The Demron specification says that it reduces the 662 keV gamma from 137Cs by only 1% (not an attenuation factor of .01, an attenuation factor of 0.99; I.E. almost no attenuation) which would be expected. High energy gamma (and 662 keV is high energy) is hard to shield. The alpha and beta effectiveness of the Demron is similar to any plastic. In the HotCat, the alpha, beta and low energy gamma (which the Demron claims to shield) will not make it out of the solid materials that comprise the structure (not even the stainless steel). However, if the reaction were producing high energy gamma (above about 100-200 keV), it would be detectable outside the HotCat. If a reaction product gamma were being produced at 6 MeV, it would go through the HotCat materials (and easily the Demron) with almost no attenuation.
The HotCat cannot use lead because it would melt, and nowhere was lead seen in Penon's report of HotCat disassembly. If one considers using some very fine nanopowder concoction for a shield, you would also have to insure that this shield is placed well away from the heat because the nanoparticles will melt at a temperature far below that of the bulk material. I don't believe the HotCat has a super-shield for high energy gamma - there is no evidence for this at all; only imagination. I believe the HotCat only produces very low energy gammas that easily get thermalized in the stainless.
