THE RUDOLF REPORT

GERMAR RUDOLF · THE RUDOLF REPORTthis quantity was found durably bound to the samples.• The cement mortar samples, in contrast to the lime mortar samples,exhibit a higher cyanide concentration by a factor of two. The higheriron content of the cement mortar samples may be the reason forthis, since the cyanide content increases proportionally to the ironcontent (see the last column of Table 19). In addition, hydrogencyanide adsorption was certainly favored by the higher inner surfacearea of the cement mortar as compared to lime mortar.• The increased hydrogen cyanide absorption caused by the additionof moisture was only slightly perceptible in the analytical results,since the samples were all very moist anyway, and because the materialdried out during the final storage phase and therefore the hydrogencyanide was only able to bind partially.• Blue pigmentation of the samples was not to be expected, since evenif all the bound cyanide were present in the form of Iron Blue, only0.005-0.01% of the total material would consist of the blue pigment,which would cause hardly any perceptible coloration to the nakedeye. An accumulation of cyanides on the surface of the sample, finally,could not occur due to the absence of water in diffusion. Inaddition, the dry storage of the samples probably blocked the conversionprocess.8.3.4. John C. BallAll samples taken from alleged homicidal ‘gas chambers’ arearound or well under the detection threshold and must therefore beconsidered zero. Ball’s samples from the delousing wings of buildings5a and 5b do represent a fairly good average of my own and confirmmy results.Table 22: Cyanide concentrations in the masonry of ‘gaschambers’/disinfestation chambers according to John C.
