Radioactive half-life: 162.7d. Monitoring: G-M Cesium-137 (137Cs). Max beta On average, tritiated water is eliminated within a 10-day biological half-life.

Cesium-137 has a radioactive half-life of about 30 years and decays by beta decay either to stable barium-137 or a meta-stable form of barium (barium-137m). particularly dangerous fission product. Cesium-137 undergoes high-energy beta decay, primarily to an excited nuclear isomer of Barium 137, which in turn undergoes gamma decay with a half-life of about 150 seconds. The energies of both the beta decay of cesium-137 and the subsequent Recommended Nuclear Decay Data Cs-137. Decay Mode: β ¯ Half-Life: (11000 ± 90) d A detailed decay scheme is given below: 55 Cs 137 (30.08 a) 1.176 0.514 MeV 94.7% 56 Ba 137m 0.662 2.55 m B 1.176 Mev Y 662 kev 5.3% 85.1% 0.284 6.892 MeV 0.0006% OT 0.11 Y284 keV 0.0006% 0.0 56 Ba 137 (stable) Further details are provided in Appendix-D of your textbook. Cesium (chemical symbol Cs) is a soft, flexible, silvery-white metal that becomes liquid near room temperature, but easily bonds with chlorides to create a crystalline powder.
