The metastable isotope ( barium -137m) is rapidly converted to stable barium-137 (half-life of about 2 minutes) accompanied by gamma ray emission whose energy is 0.662 MeV. Beta Decay of Cs137 The gure shows that two di erent decays are possible. 92% of the electrons from Cs137 are associated with a transition having an E max of 514 keV and 8% with an E max of 1176 keV. Some of the 662 keV Gammas are internally converted.

Cs 137 decay scheme

b-. X-rays from 137Cs (30.07 y 3) E (keV) Cs 137 decays by beta- emission (T=30.174y, Δ= -86.5607 MeV) to 56 Ba 137 (Δ= -87.7367 MeV) with the emission of the following radiations: β-: 1.176 Mev; max 7% 0.514 Mev; max 93% γ: 0.662 MeV; 85% Cesium-137 decays in the environment by emitting beta particles. As noted above, cesium-137 decays to a short lived decay product, barium-137m.

If very high doses are received, skin burns can result. 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.
