Atomic bombings of Hiroshima and Nagasaki
By August 1945, the Allies' Manhattan Project had produced two types of atomic bombs, and the 509th Composite Group of the United States Army Air Forces (USAAF) was equipped with the specialized Silverplate version of the Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands. Orders for atomic bombs to be used on four Japanese cities were issued on July 25. On August 6, one of the modified B-29s dropped a uranium gun-type bomb codenamed "Little Boy" on Hiroshima. Three days later, on August 9, a plutonium implosion-type bomb codenamed "Fat Man" was dropped by another B-29 on Nagasaki. The bombs immediately devastated their targets. Over the next two to four months, the acute effects of the atomic bombings killed 90,000–146,000 people in Hiroshima and 39,000–80,000 people in Nagasaki; roughly half of the deaths in each city occurred on the first day. Large numbers of people continued to die from the effects of burns, radiation sickness, and other injuries, compounded by illness and malnutrition, for many months afterward. In both cities, most of the dead were civilians, although Hiroshima had a sizable military garrison.
Environmental impact of war
After four years of World War II in August 1945, the United States of America dropped an atomic bomb over the city of Hiroshima in Japan. About 70,000 people died in nine seconds at the bombing in Hiroshima, which was comparable to that of the devastating Operation Meetinghouse air raid over Tokyo. Three days after the bombing in Hiroshima, the United States dropped a second atomic bomb on the industrial city of Nagasaki, killing 35,000.The nuclear weapon released a catastrophic load of energy. The temperature once the bombs were blasted reached about 7200°F. With temperature that high, all the flora and fauna are destroyed along with the infrastructure and human life in the impact zone. When the atomic bomb was dropped, it released enormous quantity of energy and radioactive particles. The radioactive particles released contaminated the land and water for miles. The initial blast increased the surface temperature, along with the crushing winds caused by the initial blast, trees and buildings in the path were all destroyed.
