All that remains is substantiation with the tissue report and the written directives. My guess is that these are not to be had. I also find it curious that with such elevated interest by rescuers in the presence of radioactive materials on the deceased, then who among them ghay actually spent far, far longer at the location, ate the food, drank the water and burned the wood, was checked, and decontaminated?
I agree that the record shows a Geiger Counter was used and mentioned in case files. That documentation does not suggest cover up nor conspiracy to me. It does suggest that after the rescuers spent all thay time, covering all that ground with sticks and later hooked probes, knowing the hikers had someone working in a facility which has radioactive material might leave a trace might just help. I mean otherwise a blanket of snow looks like every other blanket of snow. I could believe, but hate to say because it smacks of the "C" word that the Geiger Counter was used to see if anyone on the hike pocketed pitchblende and if so would their diary tell where the deposit was found.
