Induced radioactivity, also called artificial radioactivity or man-made radioactivity, is the process of using radiation to make a previously stable material radioactive. [1] The husband-and-wife team of Irène Joliot-Curie and Frédéric Joliot-Curie discovered induced radioactivity in 1934, and they shared the 1935 Nobel Prize in Chemistry ...
A synthetic radioisotope is a radionuclide that is not found in nature: no natural process or mechanism exists which produces it, or it is so unstable that it decays away in a very short period of time. [1] Frédéric Joliot-Curie and Irène Joliot-Curie were the first to produce a synthetic radioisotope in the 20th century. [2]
Through experiments inducing radioactivity with the recently discovered neutron, Fermi discovered that slow neutrons were more easily captured by atomic nuclei than fast ones, and he developed the Fermi age equation to describe this. After bombarding thorium and uranium with slow neutrons, he concluded that he had created new elements.
Created in 1911 by the Pasteur Institute and the University of Paris, the Radium Institute was the place where two generations of Curies, first Pierre and Marie Curie, later their daughter, Irène Joliot-Curie, and Frédéric Joliot, her husband, discovered natural and artificial radioactivity winning five Nobel prizes between 1903 and 1935 ...
The term transmutation dates back to alchemy.Alchemists pursued the philosopher's stone, capable of chrysopoeia – the transformation of base metals into gold. [3] While alchemists often understood chrysopoeia as a metaphor for a mystical or religious process, some practitioners adopted a literal interpretation and tried to make gold through physical experimentation.
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.
Discovered "radioactivity" a process in which, due to nuclear disintegration, certain elements or isotopes spontaneously emit one of three types of energetic entities: alpha particles (positive charge), beta particles (negative charge), and gamma particles (neutral charge). 1897: J. J. Thomson
Irène Joliot-Curie and Frédéric Joliot-Curie discover artificial radioactivity and are jointly awarded the 1935 Nobel Prize in Chemistry [29] 1935: Einstein, Boris Podolsky, and Nathan Rosen describe the EPR paradox, which challenges the completeness of quantum mechanics as it was theorized up to that time.
