 　After the Hiroshima atomic bomb exploded, a woman returned home and went out to do laundry in the burnt and destroyed city of Hiroshima. While carrying a child on her back, the woman squatted in a bucket and washed the clothes by hand. Taking a bath, washing hair and body, and washing clothes were routine decontamination. By rinsing with water, it was possible to remove a significant amount of radioactive material

　At 8:15 a.m. on August 15, 1945, an atomic bomb was dropped on the city of Hiroshima from an altitude of approximately 9,630 meters and exploded just before it hit the ground. Suddenly, a whitish, pinkish glare appeared in the sky, accompanied by unnatural tremors. Within seconds, thousands of people in the streets and yards of downtown Hiroshima were scorched by a wave of searing heat. Many died instantly, while others lay on the ground in agony from the excruciating pain of their burns. Walls, houses, factories, and other buildings that stood upright in the blast were all destroyed. Debris swirled and soared into the air. Trams were picked up and tossed about as if they had no weight or solidity. Everything living was dying in indescribable agony. Beams, bricks, and girders swirled and collapsed houses. Houses within three miles of the hypocenter, the center of the atomic explosion, were flattened as if they had been built with cardboard. The few who managed to escape to safety died from gamma radiation poisoning about 20 to 30 days after the bombing.

　About 30 minutes after the atomic bomb exploded, while the sky over the Hiroshima area was cloudless, a fine rain began to fall on the city and continued to fall for about five minutes. This rain was caused by heated air suddenly rising to a high altitude, where it condensed and fell as rain. When it rained, radioactive materials drifting in the air above fell with the rain, which caused the detected radioactivity level to rise. Later, fierce winds blew and the fire spread with frightening speed. In the evening the fire began to die down and then went out. There was nothing left to burn. Hiroshima had been extinguished. The atomic bombs of Hiroshima and Nagasaki caused a fission reaction in the air, and with nothing to block it, a large amount of radioactive material fell to the ground.
