As the Cs-137 nuclei decay to the Ba-137m nuclei, the Ba-137m atoms remain adsorbed on the surface of the resin. But because Barium has a different chemistry than Cesium, it is more loosely bound to the resin and can be de-adsorbed with a weakly acidic salt solution containing HCI and NaCI. 23 rows 1 Decay Scheme 133Ba disintegrates by electron capture mainly to two 133Cs excited levels of 437 keV (85.4%) and of 383 keV (14.5%) with three very minor branches to the 160 keV, 81 keV excited levels and the ground state.

(See Equations 2 and 3.) B. Half-Life of a Short-Lived Radioisotope Cesium-137 is a radioactive isotope with a half-life of 30.2 years. It undergoes β decay to produce barium-137m, an unstable nuclear "isomer" that further decays to the stable barium-137 nucleus by γ emission: 137 55 Cs → 137m 56 Ba + 0 1β 137m 56 Ba → 137 56 Ba + γ

a resin material. The Ba-137m atoms are a daughter product that results from the decay of Cs-137 according to the scheme shown in Figure 2. As the Cs-137 atoms decay to the Ba-137m atoms, the Ba-137m atoms remain adsorbed on the surface of the resin, but because barium is in a different chemical form than the cesium was previously, it is more 5 The longest-lived isomer is 133m Ba, which has a half-life of 38.9 hours, though the shorter-lived 137m Ba (half-life 2.55 minutes) arises as the decay product of the common fission product caesium-137.
