Human remains are very slightly radioactive. For perspective, so are bananas. But even more so, all of the incinerators were coal fired. ALL coal is radioactive. This is why modern coal power plants require scrubbers. And the waste removed from the scrubbers is highly (as in dangerous levels) radioactive. The result is if a large number of bodies were in fact incinerated, the entire surrounding area would have been covered with above background radiation levels. To date, only normal background levels of radiation have ever been detected at any of these camps. Thereby absolutely confirming there was never any large scale incineration taking place at or near these camps. This in itself 100% invalidates any claim to the contrary. Additionally, the entire African campaign was about securing oil, coal, and diamonds. They were desperate to obtain energy sources. They would never waste their primary sources of energy (coal and wood) to burn bodies. On top of this, the kept very accurate records of all coal deliveries to these camps. They were barely enough to keep everyone alive. Which means the records themselves document there was never enough energy to run the incinerators beyond the minimal level for health and safety. Eventually even this came up short. Which matches what was observed when the camps were captured. Bluntly, this evidence in of itself conclusively proves they were not death camps. Well, not gas chambers and incinerators anyways. As almost all supplies were delivered by rail, here is the actual cause of shortages toward the end which caused no end of issues: https://www.youtube.com/watch?v=kYTaddev6KQ
