This is an interesting legend regarding the bombings of Hiroshima and Nagasaki. From the unexplained-mysteries forum:
"When I was in the 5th or 6th grade we had a substitute teacher. A very animate man with long hair, very effeminate. But we all loved him and enjoyed having him as our sub! Anyhow, he told us a story once during our history lesson. He said he had visited the city of Hiroshima (or what was Hiroshima?) and that the shadows of the people remained as they were at the very moment the bomb hit. The shadows still existed, and hadnt moved."
This is because the bomb sent out massive amounts of radiation, which burnt anything in its path, but where something blocked it, it wasn't burned, so there are shadows permanently burn into objects which were shielded from the radiation.
Similarly, some people had the patterns on their clothes permanetly burned into the flesh because the dark parts of their clothing absorbed radiation and burnt their skin whereas the light parts of clothing reflected radiation and so protected the skin. So someone wearing a shirt with zebra stripes printed on it would have zebra stripes permanently burned into their skin.
In the picure above you can see the shadows cast by a fence at the side of a bridge. The white lines are where the fence protected the ground from radiation from the bomb.
