Atomic weapons Manhattan Project

During the early years of the Second World War, Emmett directed an important National Defense Research Committee project at Hopkins that involved the use of adsorbents in gas masks to remove poison gases. In 1943 he became a division chief in the Manhattan Project, dealing with enrichment by diffusion of uranium isotopes for use in nuclear weapons. From 1945 until his death he was a consultant to the Atomic Energy Commission on peacetime uses of atomic power. 

The first man-made nuclear fission reaction was achieved in 1938, unlocking atomic power both for destructive and creative purposes. In 1951, the first usable electricity was created via the energy produced by a nuclear reactor, thanks largely to research conducted in the Manhattan Project that developed the first atomic weapons during World Warll.

In the spring of 1945, preparations began in the Pacific for the use of the atomic bomb. On May 8, 1945, Germany surrendered, and the project was then focused solely on Japan. On July 16, 1945, a test device code-named Gadget was detonated at the Alamogordo Bombing Range in New Mexico as part of Project Trinity, the first explosion of a nuclear weapon. The success of the first test of a nuclear weapon was a testament to the ability of the leadership of the Manhattan Project to carry out an unprecedented industrial project, with the world s most talented scientists... 

Their work as part of the Manhattan Project was kept secret and was finally reported in 1946, after World War II, although the existence of plutonium had been revealed to the world earlier, when the atomic bomb was dropped over Nagasaki, Japan. There are sixteen isotopes of plutonium, having mass numbers ranging from 232 to 247. The principal isotopes of Pu are those having mass numbers 238, 239, 240, 241, 242, and 244. Ton quantities of Tu (having a half-life of 2. 4 X 0 y) are available. The isotope Tu is the source material for nuclear weapons and is produced via neu-...
