The first wave of the horrendous toll taken by the atomic bomb explosion was, of course, the concussion of the explosion and unearthly intensity of the heat of the explosion. These immediate effects were followed months and years later by illnesses resulting from exposure to radioactivity, such as the death of Sadako Sasaki, who succumbed to leukemia ten years later. In this image we see the unimaginable horror of the burns resulting from the blast, which generated heat rays so intense that they charred the patterns of fabrics on to victims' skin.
