of bombarding uranium with neutrons; notable energy release

• December 1938-Hahn and Strassmann discovered neutrons were penetrating the uranium, splitting the nuclei while producing smaller particles. These particles could be used to create a chain reaction

• 1939-Niels Bohr and John Wheeler find natural Uranium contains a ratio of 140:1 U238 and U235 isotopes respectively; U235 isotopes split when bombarded with neutrons

Discovery of Atomic Energy (Cont.)

• August 1939-Szilard, Eugene Wigner, and Edward Teller approach Albert Einstein about concerns over the development of atomic weapons in Germany

• October 1939-Einstein’s letter to President Roosevelt, dated August 2, 1939 is delivered to Roosevelt. Outlines the potential of atomic energy and the danger if other countries, especially Germany, develop the technology.

• 1940-Otto Frisch and Rudolph Peierls work to isolate U 235 isotope

• 1940-Hans von Halban and Lew Kowarski bombard natural uranium to create plutonium-U 239 (fission)

Discovery of Atomic Energy (Cont.)

• 1941-American scientists visit the UK to study current atomic research

• 1941-US begins the Manhattan Project; codename for development of the atomic bomb

• May 1942-USSR begins massive espionage program to uncover atomic energy secrets from the US

• 16 July 1945- First successful nuclear explosion- Alamogordo, NM known as “Trinity”

Manhattan Project

• Los Alamos, NM-main bomb development and assembly

• Oak Ridge, TN-separate U235 from U238• Hanford, Washington-Plutonium manufacturing• Robert J. Oppenheimer-Nuclear physicist; head

of bomb development in NM• General Leslie R. Groves-military engineer;

head of Manhattan Project• Project cost: $2,000,000,000• Employees: 600,000

Should the bomb be used?• Humanitarian

– Countless number of lives lost– Scientists were unsure of the affects of a nuclear explosion in an urban

environment• Military

– The destructive power of the bomb could lead to an end to the war– Save soldiers lives– Was not central consideration– Some argue decision was made to use the bomb before Roosevelt’s

death• Political

– The successful detonation of an atomic weapon would give the US the ability to control post war decision making

– Limit role of Soviet Union

Decision

• Truman gives the order to use the atomic bomb in Japan

• Hiroshima-6 August 1945

• Nagasaki-9 August 1945

Hiroshima

• 6 August 1945• Uranium (U235) fission bomb-“Little Boy”-

reference to Roosevelt• 9ft 9in long• 8000 lbs.• 12.5 Kilotons (.125 Megatons)• Targeted because it had not been bombed by

Allies-wanted to get an accurate assessment of the damage

• Dropped by B29 bomber-”Enola Gay”

Destruction of Hiroshima

• 5 mile radius reduced to ashes• 62.9 % of buildings destroyed• 50% death rate within ¾ mile• 118,661 deaths by August 10• 82,000 injured• Long term effects

– Radiation sickness– Genetic and chromosome injury– Unborn children experienced stunted growth and

mental disabilities

Nagasaki

• 9 August 1945• Plutonium (U239) fission bomb-“Fat Man”-

reference to Churchill• 11ft long• 9000 lbs.• 22 Kilotons (.22 Megatons)• Secondary target- Primary target of

Kokura was aborted due to heavy cloud cover

Japan Surrenders

• 14 August 1945-Emperor Hirohito announces the “unconditional surrender” of Japanese forces (Military government)

• Terminology is important in this case because Japanese were allowed to keep their Emperor (Imperial government); some viewed this fact as a condition

• Believed the Japanese would have never surrendered had the Emperor been removed from power as part of “unconditional surrender”

• Victory over Japan

• 2 September 1945 is also known as V-J Day– Japanese sign surrender aboard the USS

Missouri in Tokyo Bay– Accepted by General Douglas MacArthur
