This page discusses each of the main elements in the mixture of fission products produced by nuclear fission of the common nuclear fuels uranium and plutonium. The isotopes are listed by element, in order by atomic number. Neutron capture by the nuclear fuel in nuclear reactors and atomic bombs also produces … See more If Germanium-75 is produced, it quickly decays to Arsenic. Germanium-76 is essentially stable, only decaying via extremely slow double beta decay to Se. See more while arsenic presents no radiological hazard, it is extremely chemically toxic. If it is desired to get rid of arsenic (no matter its origin), thermal neutron irradiation of the only stable isotope As will yield short lived As which quickly decays to stable Se. If Arsenic is irradiated … See more The other stable isotope Br is "shadowed" by the long half life of its more neutron rich isobar Se. See more Rubidium-87 has such a long half life as to be essentially stable (longer than the age of the earth). Rubidium-86 quickly decays to stable Strontium-86 if produced either directly, via (n,2n) reactions in Rubidium-87 or via neutron capture in Rubidium-85. See more Se-79, half-life of 327k years, is one of the long-lived fission products.

WebCesium-137 . An inevitable byproduct of nuclear fission is the production of fission products which are highly radioactive. Cesium-137 and strontium-90 are the most dangerous radioisotopes to the environment in terms of their long-term effects. Their intermediate half-lives of about 30 years suggests that they are not only highly … WebThe fission products include every element from zinc through to the mid to late lanthanides. The majority of the mass yield of the fission products occurs in two peaks. One peak gives a peak (expressed by atomic number) at about strontium to ruthenium while the other peak is at about tellurium to neodymium. According to Jiri Hala's textbook the …

The creation of fission products changes the fuel from its original composition into a multicomponent system. Fission products may be present in the fuel in the form of solid precipitates, or gas bubbles, or in solid solution with the fuel matrix. All three forms are affected by thermodiffusion ...
WebFission product 131 I (T 1/2 = 8.02 days) is a very important radionuclide in view of radiation protection because it can be released from various nuclear installations and its volatility makes it highly mobile in the environment. Because of its relatively high bioavailability, it readily enters the biosphere and propagates through the food chain. Milk …
