Mineral water. Gross alpha, gross beta.

In the case of caesium-137, conversion electrons carries on average 5% of the decay energy. IN2P3 The example displayed of cesium-137 shows the respective weights of gamma emission and internal conversion. 94.7% of beta decays lead to an excited state of the nucleus : 85.1% return to the ground state by emitting an energetic 661.57 keV gamma, while 9.6% returns to stability through internal

emitting beta particles. As noted above, cesium-137 decays to a short-lived decay product, barium-137m. The latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium.

It decays via emission of a low-energy beta particle into the stable isotope barium-135. beta decay of caesium-137. We demonstrate that the exposure of a gold target to a copper vapour laser beam (wavelengths of 510.6 and 578.2 nm, pulse duration of 15 ns) for 2 h in an aqueous solution Caesium 137 A legacy of atmospheric nuclear bomb tests and accidents. Caesium 137 is a radioactive element with a relatively long half-life of 30.15 years. This particular isotope of caesium is both a beta and gamma emitter. It is produced in some abundance by fission reactions. 137 Cs decay from 1993-98 (NSR) Decay properties: Mode Branching (%) Q-value (keV) b-100: 1175.63 17 ; Data sets: Mode Data set name Display data; b-137CS B- DECAY: Tables: ENSDF data: Java applets: Gammas from 137 Cs (30.07 y 3) Eg,Ig Ig,Eg Decay mode,Eg.

The equation that describes the radioactive decay of cesium is shown below. The conversion of a neutron (from the cesium nucleus) to a proton causes the atomic number to increase from 55 to 56. This leads to the formation of barium-137. It's important to notice that the mass number stays the same in examples of beta decay.
