Crash cows: “There were often significant food shortages in the Soviet Union, and the government plan was to mix the meat from Chernobyl-area cattle with the uncontaminated meat from the rest of the country. This would lower the average radiation levels of the meat without wasting valuable resources.”

There is some sense to that: low levels of radiation are not a cancer risk last I read - everything we eat is slightly radioactive. That said, I can’t think how significantly radioactive cows could be “diluted“ enough.
