Cs-137 beta spectrum
WebApr 2, 2016 · Cesium-137 has an atomic number of 55, so is written as #""_55^137Cs#. It is also a #beta#-emitter, which means it undergoes #beta#-decay by a neutron decaying into a proton, releasing an electron.. Protons and neutrons have the same mass, so the mass number doesn't change. The atomic number increases by one, because one more proton … WebFor a beta-gamma detector, the gamma energy calibration is initially determined using a 137 Cs source, and a radioactive gas spike of 222 Rn and 131m Xe. These sources give seven gamma- and x-ray ...
