The shadows of Hiroshima - the effect arising from the action of light radiation in a nuclear explosion ; they represent silhouettes on a burnt out background in places where the body of a person or an animal or any other object interfered with the spread of radiation. The effect was named after the Japanese city of Hiroshima , where such formations first appeared on August 6, 1945 .
The phenomenon is similar to the appearance of an ordinary shadow : a certain object appears on the path of radiation, which shields the surface area behind it from the radiation. In an atomic explosion, the radiation intensity is so great that many surfaces change their color and properties. For example, the asphalt surface darkens, polished granite becomes rough, and the painted surface burns out [1] . In Hiroshima, people who were exposed to light radiation within a radius of impact, suffered severe burns before charring and were then thrown away by the shock wave, leaving unburned shadows. Many remained alive after that, but still after a while they died from burns, radiation and injuries; many burned in the fires and the fire storm that erupted after the explosion. In Hiroshima, the epicenter of the explosion fell on the Aoya bridge , where the shadows of nine people remained.
Something similar happens during normal chemical explosions and strong fires, when charred corpses found after a fire cover up the unburned and uncovered surface of the floor and walls.
