137 Cs decay scheme showing half-lives, daughter nuclides, and types and proportion of radiation emitted. 137 Cs gamma spectrum. The characteristic 662 keV peak does not originate directly from 137 Cs, but from the decay of 137m Ba to its stable state. Caesium-137 has a half-life of about 30.17 years.

Cesium-137 is used in small amounts for calibration of radiation detection equipment, such as Geiger-Mueller counters. In larger amounts, Cs-137 is used in: Medical radiation therapy devices for treating cancer. Industrial gauges that detect the flow of liquid through pipes. The beta-ray spectrum is shown in Fig. 1. The shape suggests a beta-spectrum of a simple type on which is superposed at the high energy end a strong internal con-version line. A Kurie plot is reproduced in Fig. 2.
