what is the effect of manhattan project?

Question

the result of that project

Answer 1

The result was the creation of the first atomic bomb, which Truman dropped on Japan to end WW II

Answer 2

The United States in late 1941 established a secret program, which came to be known as the Manhattan Project, to develop an atomic bomb, a powerful explosive nuclear weapon. The aim of the project, directed by physicist J. Robert Oppenheimer, was to build an atom bomb before Germany did.

Answer 3

The Manhattan Project was the project to develop the first nuclear weapon (atomic bomb) during World War II by the United States, the United Kingdom and Canada. Formally designated as the Manhattan Engineer District (MED), it refers specifically to the period of the project from 1941–1946 under the control of the U.S. Army Corps of Engineers, under the administration of General Leslie R. Groves. The scientific research was directed by American physicist J. Robert Oppenheimer.

The project succeeded in developing and detonating three nuclear weapons in 1945: a test detonation of a plutonium implosion bomb on July 16 (the Trinity test) near Alamogordo, New Mexico; an enriched uranium bomb code-named "Little Boy" on August 6 over Hiroshima, Japan; and a second plutonium bomb, code-named "Fat Man" on August 9 over Nagasaki, Japan.

The project's roots lay in scientists' fears since the 1930s that Nazi Germany was also investigating nuclear weapons of its own. Born out of a small research program in 1939, the Manhattan Project eventually employed more than 130,000 people and cost nearly $2 billion USD ($23 billion in 2007 dollars based on CPI). It resulted in the creation of multiple production and research sites that operated in secret.[1]

The three primary research and production sites of the project were the plutonium-production facility at what is now the Hanford Site, the uranium-enrichment facilities at Oak Ridge, Tennessee, and the weapons research and design laboratory, now known as Los Alamos National Laboratory. Project research took place at over thirty different sites across the United States, Canada, and the United Kingdom. The MED maintained control over U.S. weapons production until the formation of the Atomic Energy Commission in January 1947.

Answer 4

It wasn't the dropping of the bomb it was the secret study of effects of the chemicals of the bomb.

TOXIC SECRETS
Fluoride & the A-Bomb Program
During the ultra-secret Manhattan Project, a report was commissioned to assess the effect of fluoride on humans.
That report was classified "secret" for reasons of "national security".

***************************************
Fluoride was the key chemical in atomic bomb production, according to the documents. Massive quantities-millions of tons-were essential for the manufacture of bomb-grade uranium and plutonium for nuclear weapons throughout the Cold War. One of the most toxic chemicals known, fluoride emerged as the leading chemical health hazard of the US atomic bomb program, both for workers and for nearby communities, the documents reveal.
Declassified documents of the US atomic bomb program indicate otherwise. A Manhattan Project memorandum of 29 April 1944 states: "Clinical evidence suggests that uranium hexafluoride may have a rather marked central nervous system effect... It seems most likely that the F [code for fluoride] component rather than the T [code for uranium] is the causative factor." The memo, from a captain in the medical corps, is stamped SECRET and is addressed to Colonel Stafford Warren, head of the Manhattan Project's Medical Section.

Answer 5

The results ended WW II. Without the bomb many more lives would have been lost.

Answer 6

It created the first atomic bomb, which eneded the war with Japan, and eventually led to the arms race in the Cold War.

Answer 7

its still classified, 2015...
