Cs 137 decay

Gamma photons emitted from the barium decay product, Ba-137m, are a form of ionizing radiation that can pass through the human body, delivering doses to internal tissue and organs. People may also be exposed internally if they swallow or inhale cesium-137. 137 Cs decay from 1993-98 (NSR) Decay properties: Mode Branching (%) Q-value (keV) b-100: X-rays from 137 Cs (30.07 y 3) E (keV) I (%) Assignment; 3,954 : 0.0143 A total of 85.1% of all 137 Cs nuclei decay in this way (i.e. 85.1% of all 137 Cs nuclear decays result in 661.7 keV gamma rays). In 5.4% if the cases 137 Cs decays directly into the ground state of 137 Ba by emitting a 1.174 MeV β-particle with no associated gamma.
