Monday morning, August 6, 1945, began with clear skies. As the midsummer sun rose, the temperature climbed steadily. An air raid siren issued at 12:25 AM had been lifted at 2:10 AM. People who had finally managed to drift off to sleep were jolted awake again at 7:09 AM by a cautionary siren. However, since only a single American aircraft passed by at high altitude, the warning was lifted at 7:31 AM. Relieved, people returned home from air-raid shelters and evacuation sites to eat a late breakfast or head out to work, beginning their day. At that moment, the alarm bell for an incoming warning suddenly rang in the information room of the Hiroshima Central Broadcasting Station. Announcer Furuta rushed into the office, grabbed the script, entered the studio, and pressed the buzzer. "Chugoku Military District Information! Three large enemy aircraft over Saijo..." The moment he read those words, a terrifying grinding sound erupted, the reinforced concrete building tilted, and his body was flung into the air. August 6, 1945, 8:15 AM. For the first time in human history, an atomic bomb was dropped on Hiroshima. Forty-three seconds after release, the atomic bomb detonated 600 meters above the ground with a blinding flash, creating a scorching fireball like a miniature sun. The temperature at the center of the fireball exceeded one million degrees Celsius. Within one second, it grew to a radius of over 200 meters, and the surface temperature near the hypocenter reached 3,000 to 4,000 degrees. At the instant of explosion, intense heat rays and radiation were emitted in all directions, while the surrounding air expanded into a super-high-pressure blast. The complex interaction of these three elements caused catastrophic damage. The defining characteristics of the atomic bomb's destruction were the instantaneous and indiscriminate mass slaughter and devastation, and the fact that radiation-induced illnesses continued to torment survivors for long years afterward.
