WebFeb 27, 2016 · photodisintegration. photoelectric interaction. photoelectron. radiolucent. radiopaque. secondary photons. transmission. Introduction. It is helpful for the radiographer to understand the way x-ray photons interact … Photodisintegration (also called phototransmutation, or a photonuclear reaction) is a nuclear process in which an atomic nucleus absorbs a high-energy gamma ray, enters an excited state, and immediately decays by emitting a subatomic particle. The incoming gamma ray effectively knocks one or more … See more A photon carrying 2.22 MeV or more energy can photodisintegrate an atom of deuterium: 1D + γ → 1H + n James Chadwick and Maurice Goldhaber used this reaction to … See more A photon carrying 1.67 MeV or more energy can photodisintegrate an atom of beryllium-9 (100% of natural beryllium, its only stable isotope): 4Be + γ → 2 2He + n Antimony-124 is assembled with beryllium to make laboratory See more Photofission is a similar but distinct process, in which a nucleus, after absorbing a gamma ray, undergoes nuclear fission (splits into two fragments of nearly equal mass). See more In explosions of very large stars (250 or more solar masses), photodisintegration is a major factor in the supernova event. As the star reaches the end of its life, it reaches … See more Terrestrial lightnings produce high-speed electrons that create bursts of gamma-rays as bremsstrahlung. The energy of these rays is sometimes sufficient to start photonuclear … See more • Pair-instability supernova • Silicon-burning process See more WebF- directly transmitted photons must interaction with the IR b.
