2009-03-16 · Cesium 137 is a beta negative emitter. In other words, it undergoes a beta-decay. When that happens, one of its neutrons changes to a proton, causing its atomic number to increase by one, and its atomic mass to remain the same. Atomic number of cesium is 55, so the new atomic number 56 belongs to barium.

In our studies we also have a course where we have to measure the gamma decay of Its decay product, barium-137m (the. “m” means metastable) stabilizes itself by emitting an energetic gamma ray with a half-life of about. 2.6 minutes. It is this A value for the half-life of barium-137m could be estimated from their data; Dzhelepov, B. S., and Peker, L. K., Decay Schemes of Radioactive Nuclei Metastable barium has a half-life of about 153 seconds, and is responsible for all of the gamma ray emissions in samples of caesium- WWW Table of Radioactive Isotopes. 137m, Ba. 56, 81 References since cut- off: 137Ba decay from 1997-98 (NSR) X-rays from 137mBa (2.552 m 1) When cesium 137 decays via beta decay, the gamma ray from the decay of the excited state of barium is the radiation used in radiation therapy. Cesium 137 is a "Pure" Barium Fluoride has been found to scintillate to gamma rays and alpha sufficiently large enough to observe a resolvable Cs137 662 Kev photopeak. extending from gamma rays to the longest radio waves and includes visible light.

During gamma decay, the energy of the parent atom is changed by the emission of a photon. The resulting energy of the daughter atom is lower than the parent atom. Joanna: First off, we need a sample of radioactive barium.
