Cesium 134
Cesium (Cs, atomic number 55) is an alkali metal having 40 isotopes, ranging in mass from 112 to 151. Of these, the fission product cesium-137 (half-life 30.17 years) is of greatest concern. Cesium-137 is one of the nuclides most responsible for the radioactivity of used reactor fuel and high-level waste (with the other being strontium-90).
