  • Cesium137 deposition and contamination of Japanese PNAS

    The largest concern on the cesium137 (137Cs) deposition and its soil contamination due to the emission from the Fukushima Daiichi Nuclear Power Plant (NPP) showed up after a massive quake on March 11, 2011. Cesium137 (137Cs) with a halflife of 30.1 y causes the largest concerns because of its deleterious effect on agriculture and stock farming, and, thus, human life for decades.

  • What is the decay equation of cesium 137? Socratic

    Cesium137 has an atomic number of 55, so is written as #""_55^137Cs#. It is also a #beta#emitter, which means it undergoes #beta#decay by a neutron decaying into a proton, releasing an electron.. Protons and neutrons have the same mass, so the mass number doesn't change. The atomic number increases by one, because one more proton is formed.
