However, in 2009, Petteri Tiippana, the director of nuclear power plant division in the Finnish Radiation and Nuclear Safety Authority, told the BBC that it was difficult to deliver a Generation III reactor project on schedule because builders were not used to working to the exacting standards required on nuclear construction sites, since so ...
The history of nuclear physics as a discipline distinct from atomic physics, starts with the discovery of radioactivity by Henri Becquerel in 1896, [1] made while investigating phosphorescence in uranium salts. [2] The discovery of the electron by J. J. Thomson [3] a year later was an
Gamma radiation emission is a nuclear process that occurs to rid an unstable nucleus of excess energy after most nuclear reactions. Both alpha and beta particles have an electric charge and mass, and thus are quite likely to interact with other atoms in their path.
In 1921, he was studying radioactivity at the Kaiser Wilhelm Institute for Chemistry in Berlin, Germany, when he noticed somethi Nuclear isomers were discovered 100 years ago, and physicists are ...
The discovery came after forty years of investigation into the nature and properties of radioactivity and radioactive substances. The discovery of the neutron by James Chadwick in 1932 created a new means of nuclear transmutation.
Rutherford's discoveries include the concept of radioactive half-life, the radioactive element radon, and the differentiation and naming of alpha and beta radiation. Together with Thomas Royds, Rutherford is credited with proving that alpha radiation is composed of helium nuclei.
Antoine Henri Becquerel (/ ˌ b ɛ k ə ˈ r ɛ l /; [3] French: [ɑ̃ʁi bɛkʁɛl]; 15 December 1852 – 25 August 1908) was a French physicist who shared the 1903 Nobel Prize in Physics with Pierre and Marie Curie for his discovery of radioactivity. [4] The SI unit of radioactivity, the becquerel (Bq), is named after him.
The discovery of fission electrified the global community of atomic physicists and the public. [9] In their second publication on nuclear fission, Hahn and Strassmann predicted the existence and liberation of additional neutrons during the fission process. [99] Frédéric Joliot and his team proved this phenomenon to be a chain reaction in ...
