@TomSea @mystery-akMy son, the documentary producer/director, has made two or three films (I think three) with the reindeer herders in Siberia. They are a nomad group, following the reindeer and living in tents as they travel. His most recent film with them was this year. He has a special suit to wear in those severe temperatures. These deer were not affected by fallout.
Here is a story from the film of this year, 2017:
There was one woman in the film group. They traveled with a tent just like the nomads. No one can use the bathroom anywhere near the deer as they will come and eat your urine or fecal matter while you are doing it - you can't prevent them from doing it and they should not have that issue in their bodies. If a member had to use the bathroom, he had to walk a long way, I think it was 4 or 500 yards from the deer before they could use the bathroom. The woman had to walk by herself all this way on the snow and she never complained about it. She is a tough cookie.
