Cesium 137 Beta Decay. It is a soft, malleable metal with silvery white color. Online radioactive decay calculator that allows you to find out the radioactivity decay in cesium (cs) 137.
Use Of Cesium 137 Methodology In The Evaluation Of Superficial Erosive Processes from www.scielo.br When that happens, one of its neutrons changes to a proton, causing its atomic number to increase by one, and its atomic mass to remain the same. This particular isotope of caesium is both a beta and gamma emitter. The neutron inside of the nucleus converted into the proton an thus emit the electron which is these radiations can penetrate into the human skin.
Protons and neutrons have the same mass, so the mass number.
Okay thanks, would you be able to give some examples of situations when this happens? Caesium decays by beta emission to metastable 137mbarium (95% of the time), emitting an electron with energy of 0.512 mev. In both cases, the decay of caesium 137 found in the body is much quicker than the natural radioactive decay with a period of 30 years. Protons and neutrons have the same mass, so the mass number.
