The intense pulse of high-energy neutrons generated by a neutron bomb is the principal killing mechanism, not the fallout, heat or blast. The inventor of the neutron bomb, Sam Cohen, criticized the description of the W70 as a neutron bomb since it could be configured to yield 100 kilotons: the W-70 ... is not even remotely a "neutron bomb."
Cohen's neutron bomb is not mentioned in the unclassified manual by Glasstone and Dolan, The Effects of Nuclear Weapons 1957–1977, but is included as an "enhanced neutron weapon" in chapter 5 of the declassified (formerly secret) manual edited by Philip J. Dolan, Capabilities of Nuclear Weapons, U.S. Department of Defense, effects manual DNA-EM-1, updated 1981 (U.S. Freedom of Information Act).
1932 – James Chadwick discovers the neutron, leading to experiments in which elements are bombarded with the new particle. [5] [6] 1933 – Leó Szilárd realizes the concept of the nuclear chain reaction, although no such reaction was known at the time. He invented the idea of an atomic bomb in 1933 while crossing a London street in Russell ...
On August 29, 1949, the effort brought its results, when the USSR successfully tested its first fission bomb, dubbed "Joe-1" by the U.S. [38] The news of the first Soviet bomb was announced to the world first by the United States, [39] which had detected atmospheric radioactive traces generated from its test site in the Kazakh Soviet Socialist ...
The neutron bomb purportedly conceived by Sam Cohen is a thermonuclear weapon that yields a relatively small explosion but a relatively large amount of neutron radiation. Such a weapon could, according to tacticians, be used to cause massive biological casualties while leaving inanimate infrastructure mostly intact and creating minimal fallout.
[4] [5] Like all nuclei, preceding the discovery of the neutron, it is assumed to be composed entirely of protons and hypothetical "nuclear electrons". On February 27, James Chadwick publishes the discovery of the neutron , identified as the "beryllium radiation" emitted under alpha-particle bombardment, previously observed by Irène Joliot ...
He has been called the "architect of the nuclear age" [1] and the "architect of the atomic bomb". [2] He was one of very few physicists to excel in both theoretical physics and experimental physics. Fermi was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and for the discovery of ...
Sir James Chadwick (20 October 1891 – 24 July 1974) was an English physicist who received the Nobel Prize in Physics in 1935 for his discovery of the neutron.In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atom bomb research efforts.
