When it was: August 15, 1945
Brief Description: The bombings of Hiroshima and Nagasaki were nuclear attacks occurred at the end of World War II against the Empire of Japan conducted by the Air Force of the United States in the order of U.S. President Harry S. Truman on 6 August and 9 August 1945. After six months of intense bombing in 67 other Japanese cities, the atomic bomb "Little Boy" on Hiroshima fell on a Monday. Three days later, on 9, "Fat Man" dropped on Nagasaki. Historically, these are so far the only attacks that rely on nuclear weapons. Estimates of the first massacre of weapons of mass destruction on a civilian population, indicate a total number of dead range from 140,000 in Hiroshima and 80,000 in Nagasaki, some estimates are considerably higher when recorded deaths due later exposure to radiation. Most of the dead were civilian.
Consequences: The consequences of dropping the atomic bombs were devastating. Still feels the effects of radiation to which people were exposed at the time because the effects passed down from generation to generation through the hereditary characteristics.
But the consequences were not only the humanitarian level, because cities were devastated, only some of the reinforced concrete buildings in Hiroshima built keeping in mind the danger of even the earthquakes are located in the city center, not collapsed. As the bomb detonated in the air, the blast was directed more vertically (top to bottom) than in the horizontal factor largely responsible for the survival of what is now known as "Summit Genbaku" or "bomb Dome" designed and built by the Czech architect Jetzel Lan, which was only 150 m from the hypocenter of the explosion. The ruin was named Hiroshima Peace Memorial and made a World Heritage Site by UNESCO in 1996, the objections by the U.S. and
