The nuclear explosion released a huge amount of radiation, much of it in the visible light and infra red spectrum (longer than visible light). Many people came to hospitals days later with 2nd degree burns, like a sunburn, all over one side of their bodies. Closer to the center of the blast, this radiation just charred people. But the blast only lasted a few milliseconds, so a person standing in front of a wall might have a 'shadow' burned in the wall--that is, the wall was burned -surrounding- their shadow.
In his book The Martian Chronicles, Ray Bradbury wrote one short story called 'There Will Come Soft Rains' about a house filled with robotic appliances that continue to function after the family has been killed in a nuclear war. On the outside wall of the house are silhouettes of a man pushing a lawn mower and two children, one tossing a ball, the other holding her hands in the air to catch it. I was raised at a time when most Americans seemed to believe a nuclear war with the USSR was inevitable, and reading that story cost me a few nights of sleep!
Funny thing, all the survivors of Hiroshima testified they saw a bright, bright light, brighter than the sun, followed by a hot wind. But none of them said they heard anything!
