Manhattan project what were the social and cultural effects of the development of the nuclear bomb

The result was the top-secret "Manhattan Project. The world had entered the nuclear age. At the Soviet equivalent of Los Alamos, Arzamasphysicist Yuli Khariton led the scientific effort to develop the weapon.

An intermediate step in putting this method into production was taken with the construction of a medium-size reactor at Oak Ridge.

In December the British mission of 19 scientists arrived in Los Alamos. At this point, however, the exact mechanism was still not known: Most tests were considerably more modest, and worked for direct technical purposes as well as their potential political overtones. The explosion came as an intense light flash, a sudden wave of heat, and later a tremendous roar as the shock wave passed and echoed in the valley.

It was assumed that the uranium gun-type bomb could then be adapted from it. It was developed at the metallurgical laboratory of the University of Chicago under the direction of Arthur Holly Compton and involved the transmutation in a reactor pile of uranium With the development of more rapid-response technologies such as rockets and long-range bombersthis policy began to shift.

The Oak Ridge site employed tens of thousands of people at its peak, most of whom had no idea what they were working on. A mushroom cloud reached 40, feet, blowing out windows of civilian homes up to miles away. Leaving nothing to chance, Los Alamos atomic scientists conducted a pre-test test in May to check the monitoring instruments.

Einstein penned a letter to President Roosevelt urging the development of an atomic research program later that year. It also encouraged the production of thousands of nuclear weapons by both the U.

The two fission bomb assembly methods. Wells was inspired to write about atomic weapons in a novel, The World Set Freewhich appeared shortly before the First World War. Chemical explosives were used to implode a sub-critical sphere of plutonium, thus increasing its density and making it into a critical mass.

Massive new physics machines were assembled at secret installations around the United States for the production of enriched uranium and plutonium. The bomb generated an explosive power equivalent to 15, to 20, tons of trinitrotoluene TNT ; the tower was completely vaporized and the surrounding desert surface fused to glass for a radius of yards metres.

Most of these problems had to be solved before any appreciable amount of fissionable material could be produced, so that the first adequate amounts could be used at the fighting front with minimum delay.

Beforework on the design and functioning of the bomb itself was largely theoretical, based on fundamental experiments carried out at a number of different locations. They concluded that, while Germany had an atomic bomb program headed by Werner Heisenbergthe government had not made a significant investment in the project, and it had been nowhere near success.

Because testing was seen as a sign of technological development the ability to design usable weapons without some form of testing was considered dubioushalts on testing were often called for as stand-ins for halts in the nuclear arms race itself, and many prominent scientists and statesmen lobbied for a ban on nuclear testing.

As a result, development of Fat Man was given high priority. Speculation began to run towards what fallout and dust from a full-scale nuclear exchange would do to the world as a whole, rather than just cities and countries directly involved. When the cloud returned to earth it created a half-mile wide crater metamorphosing sand into glass.

Many of these companies had very lax safety measures and employees were sometimes exposed to radiation levels far above what was allowed then or now. The device yielded 15 megatons, more than twice its expected yield, and became the worst radiological disaster in U.

Manhattan Project

In the s, the U. The Manhattan Project Here is a month-by-month detailed account of the status of the atomic bomb leading up to the detonation of "Gadget" in the deserts of Alamogordo, New Mexico in July, Methods of rapidly bringing together amounts of fissionable material to achieve a supercritical mass and thus a nuclear explosion had to be devised, along with the actual construction of a deliverable weapon that would be dropped from a plane and fused to detonate at the proper moment in the air above the target.

Inall nuclear and many non-nuclear states signed the Limited Test Ban Treatypledging to refrain from testing nuclear weapons in the atmosphere, underwater, or in outer space. It highlighted the dangers posed by nuclear weapons and called for world leaders to seek peaceful resolutions to international conflict.

In the end, President Truman made the final decision, looking for a proper response to the first Soviet atomic bomb test in These included scientists such as Wernher von Braunwho had helped design the V-2 rockets the Nazis launched across the English Channel.

These policies and strategies were satirized in the Stanley Kubrick film Dr.

51f. The Manhattan Project

Kennedy and Nikita Khrushchev.the war department in the Manhattan Project to develop an atomic bomb. After four years of intensive and ever-mounting research and development efforts, an atomic device was set off on July 16,in a desert area near Alamogordo, New Mexico, generating an explosive power equivalent to that of more.

Environmental Consequences. Environmental Consequences. History Page Type: the United States was in the middle of a war and the Manhattan Project mandated that an atomic bomb be built as soon as possible.

the studies initiated by Groves at Hanford during the Manhattan Project were too short to investigate the long-term effects on. Major General Leslie Groves oversaw the Manhattan Project for the US government.

Private corporations, foremost among them DuPont, helped prepare weapons-grade uranium and other components needed to make the bombs. Nuclear materials were processed in reactors located in Oak Ridge, Tennessee and Hanford, Washington. Background Information: The Department of Energy traces its origins to World War II and the Manhattan Project effort to build the first atomic bomb.

As the direct descendent of the Manhattan Engineer District, the organization set up by the Army Corps of Engineers to develop and build the bomb, the Department continues to own and manage the Federal properties at most of the major Manhattan.

History of nuclear weapons. Jump to navigation Jump to search. A the Manhattan project brought together some of the top scientific minds of the day, to prevent the other power from acquiring nuclear supremacy. This had massive political and cultural effects during the Cold War. The Manhattan Project was the Allied effort to develop the atomic bomb during World War II.

Led by Maj. Gen. Leslie Groves and J. Robert Oppenheimer, it developed research facilities across the United States.

The Project was successful and made the atomic bombs used at Hiroshima and Nagasaki. On.
