Fission products wikipedia

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 ... 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 …

Some of the fission products leaked from the primary sodium loop into the … Nuclear fission products are the atomic fragments left after a large atomic nucleus undergoes nuclear fission. Typically, a large nucleus like that of uranium fissions by splitting into two smaller nuclei, along with a few neutrons, the release of heat energy (kinetic energy of the nuclei), and gamma rays. The two smaller nuclei are the fission products. (See also Fission products (by element)).
