The nuclear reaction theorised by Meitner and Frisch and observed by Hahn and Strassmann. Nuclear fission was discovered in December 1938 by chemists Otto Hahn and Fritz Strassmann and physicists Lise Meitner and Otto Robert Frisch. Fission is a nuclear reaction or radioactive decay process in which the nucleus of an atom splits into two or ...
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission was discovered by chemists Otto Hahn and Fritz Strassmann and physicists Lise ...
It is considered as the worst nuclear disaster in history both in terms of cost and casualties. [79] The initial emergency response, together with later decontamination of the environment, ultimately involved more than 500,000 personnel and cost an estimated 18 billion Soviet rubles—roughly US$68 billion in 2019, adjusted for inflation.

Leon M. Lederman. Eugene Theodore Booth, Jr. (28 September 1912 – 6 March 2004) was an American nuclear physicist. He was a member of the historic Columbia University team which made the first demonstration of nuclear fission in the United States. During the Manhattan Project, he worked on gaseous diffusion for isotope separation.
The National Museum of Nuclear Science & History (formerly named National Atomic Museum) is a national repository of nuclear science information chartered by the 102nd United States Congress under Public Law 102-190, [ 3 ] and located in unincorporated Bernalillo County, New Mexico, with an Albuquerque postal address.
Nuclear fission is a substantial part of the world’s energy mix, but out in the broader universe, fission is much harder to come by. Now, a new study from Los Alamos National Laboratory and ...
Lise Meitner (/ ˈliːzə ˈmaɪtnər / LEE-zə MYTE-nər, German: [ˈliːzə ˈmaɪtnɐ] ⓘ; born Elise Meitner, 7 November 1878 – 27 October 1968) was an Austrian-Swedish physicist who was instrumental in the discoveries of nuclear fission and protactinium. Completing her doctoral research in 1905, Meitner became the second woman from the ...
April 3, 1992. Designated NHL. August 19, 2008 [3] The B Reactor at the Hanford Site, near Richland, Washington, was the first large-scale nuclear reactor ever built. The project was a key part of the Manhattan Project, the United States nuclear weapons development program during World War II.
