WebFusion boosting. If a deuterium-tritium mixture is placed at the center of the device to be compressed and heated by the fission explosion, a fission yield of 250 tons is sufficient to cause D-T fusion releasing high-energy fusion neutrons which will then fission much of the remaining fission fuel. This is known as a boosted fission weapon. If a fission device … WebThe most recent, tabulated nuclear data for independent fission product yields are shown below with multiple tabs for: (1) GEFY-5.3 full energy-dependent fission yield films covering 59 targets, (2) GEFY-5.2 energy … small arms profile

See more Iodine-131 ( I, I-131) is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California, Berkeley. It has a radioactive decay half-life of about eight days. It is … See more Most I production is from neutron irradiation of a natural tellurium target in a nuclear reactor. Irradiation of natural tellurium produces almost entirely I as the only radionuclide with a half-life longer than hours, since most lighter isotopes of tellurium become … See more Iodine-131 is used for unsealed source radiotherapy in nuclear medicine to treat several conditions. It can also be detected by gamma cameras for diagnostic imaging, however it is rarely … See more • Isotopes of iodine • Iodine in biology See more I decays with a half-life of 8.02 days with beta minus and gamma emissions. This isotope of iodine has 78 neutrons in its nucleus, while the only stable nuclide, I, has 74. On … See more Iodine in food is absorbed by the body and preferentially concentrated in the thyroid where it is needed for the functioning of that gland. When I is present in high levels in the environment … See more Used for the first time in 1951 to localize leaks in a drinking water supply system of Munich, Germany, iodine-131 became one of the most … See more WebTHE JEF-2.2 FISSION YIELD LIBRARIES Introduction This chapter summarises the methodology underlying the JEF-2.2 fission product yield evaluation, which was adopted from the UK evaluation UKFY2. In the UK the evaluation of fission product yields for use in computer libraries was pioneered by E.A.C. Crouch at Harwell [1]. solidworks hexagon pattern
