USA HISTORY

Detailed explanation-1: -The explosion immediately killed an estimated 80, 000 people; tens of thousands more would later die of radiation exposure. Three days later, a second B-29 dropped another A-bomb on Nagasaki, killing an estimated 40, 000 people.

Detailed explanation-2: -The two bombings killed between 129, 000 and 226, 000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict. Japan surrendered to the Allies on 15 August, six days after the bombing of Nagasaki and the Soviet Union’s declaration of war against Japan.

Detailed explanation-3: -By the end of 1945, the bombing had killed an estimated 140, 000 people in Hiroshima, and a further 74, 000 in Nagasaki. In the years that followed, many of the survivors would face leukemia, cancer, or other terrible side effects from the radiation.

Detailed explanation-4: -The bomb never hit the ground, but exploded about 2, 000 feet above the city – a height intended to cause maximum damage. (Ironically, the Yagi antenna used to achieve this midair detonation was designed and patented by a Japanese inventor.)
