Nagasaki devastation

The nuclear explosions that devastated Hiroshima and Nagasaki killed 100,000 to 200,000 people instantaneously. Probably an equal number died later, victims of the radiation released in those explosions. Millions of people were exposed to the radioactivity released by the accident at the Chernobyl nuclear power plant. The full health effects of that accident may never be known, but 31 people died of radiation sickness within a few weeks of the accident, and more than 2000 people have developed thyroid cancer through exposure to radioactive iodine released in the accident. Even low levels of radiation can cause health problems. For this reason, workers in facilities that use radioisotopes monitor their exposure to radiation continually, and they must be rotated to other duties if their total exposure exceeds prescribed levels. 

II. On August 6, 1945, an atomic bomb (nicknamed as Little Boy ) was dropped by an American B-29 bomber (Enola Gay) over Hiroshima, Japan instantly killing more than 70000 people. On August 9, 1945, the USA dropped a second atomic bomb (nicknamed Fat Man ) killing some 40000 people in Nagasaki, Japan. Because of this large-scale devastation, such nuclear explosive devices have never again been used in a war. 

During World War II an intense research effort (the Manhattan Project) was carried out by the United States to build a bomb based on the principles of nuclear fission. This program produced the fission bombs that were used with devastating effects on the cities of Hiroshima and Nagasaki in 1945. Basically, a fission bomb operates by suddenly combining two subcritical masses of fissionable material to form a supercritical mass, thereby producing an explosion of incredible intensity. 

August 9, 1945 Three days later, a plutonium bomb devastates Nagasaki. More than 39,000 people died, and 25,000 were injured. 

Production of plutonium was begun in Chicago in 1942 in an atomic pile. The bomb that devastated Nagasaki in Japan on 9th August 1945 contained plutonium. 

It is hard for me to believe today bow little I knew then about the bomb and its devastation. There had already been a thorough and authoritative survey of the short-term medical impact of the two bombs on the people of Hiroshima and Nagasaki. But the reports were all classified, and none of their contents had been made available to me. 

The detonation of nuclear bombs over Hiroshima and Nagasaki in August 1945 during World War II led to the immediate deaths of approximately 200,000 people, primarily civilians, as well as lasting injury and later death of many others and massive devastation - and widespread radioactive contamination - of the environment in these two cities [5], In addition to the potential for the use of nuclear weapons by national armed forces, such as that described in the recent U.S. Nuclear Posture Review, which threatened use of nuclear weapons under a wider range of circumstances, there is an increasing threat of their use by individuals and groups [6]. 

Roosevelt died before the United States loosed its atomic weapons on Hiroshima and Nagasaki, so he never saw the bomb s devastating powers or its psychological impact on the world. Many of those who did soon echoed Roosevelt s beliefs, suggesting that conventional warfare—in which armies are summoned to face one another on the battlefield— would no longer be a part of life on earth. 

Their work led to the explosion of the first atomic bomb in the New Mexico desert at 5 30 a.m. on July 16,1945. Less than a month later (August 6,1945), the world learned of this new weapon when another bomb was exploded over Hiroshima. This bomb killed 70,000 people and completely devastated an area of 10 square kilometers. Three days later, Nagasaki and its inhabitants met a similar fate. On August 14, Japan surrendered, and World War II was over.
