Caesium-137 ( 55Cs ), cesium-137 (US), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from spontaneous fission of uranium-238. It is among the most problematic of the short-to-medium-lifetim… WebThe reproducibility of the method was 5% for digestible matrices and 10–20% for litter where the fraction of Cs isotopes released was small.

Web21 Jun 2024 · There are a couple of important differences. First, there's more energy to be released in the decay of 134 Cs, Q = 2.1 M e V, than in the decay of 137 Cs, Q = 1.2 M e V . As a rule of thumb, more energetic decays proceed more rapidly. However, the fact that neither decay goes directly to the ground state (the most energetic route) suggests ...
