WebRadium (88 Ra) has no stable or nearly stable isotopes, and thus a standard atomic weight cannot be given. The longest lived, and most common, isotope of radium is 226 Ra with a half-life of 1600 years. 226 Ra occurs in the decay chain of 238 U (often referred to as the radium series). Radium has 33 known isotopes from 202 Ra to 234 Ra. .

This uranium makes up the bulk of the material separated during reprocessing. Commercial LWR spent nuclear fuel contains on average (excluding ...
WebNuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei.The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic … WebIsotopes of uranium. Uranium ( 92 U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found.
WebSome fission products are themselves stable or quickly decay to stable nuclides. Of the (roughly half a dozen each) medium lived and long-lived fission products, some, like 99 Tc, are proposed for nuclear transmutation precisely because of their non-negligible capture cross section. Other fission products with relatively high absorption cross ... Webfission product, in physics, any of the lighter atomic nuclei formed by splitting heavier nuclei (nuclear fission), including both the primary nuclei directly produced (fission fragments) and the nuclei subsequently generated by their radioactive decay. The fission fragments are highly unstable because of their abnormally large number of neutrons …
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.
