Joanna: First off, we need a sample of radioactive barium. We're going to get it from this thing. This device contains a salt made from radioactive cesium-137. As it decays, the cesium turns into barium-137 through beta decay. Now, barium-137 is a little unusual. Some of the barium-137 atoms that are produced are stable and don't decay any further.

Synthesis and characterization of zirconyl molybdopyrophosphate and its application for preparing 137Cs/137m Ba radioisotope generator. Radiochemistry 2012, 54 (6) , 573-577.; Rubel Chakravarty, Ramu Ram, K.T. Pillai, Yugandhara Pamale, R.V. Kamat, Ashutosh Dash. Cesium-137 is a radioactive isotope with a half-life of 30.2 years.

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.

Cesium- 137 has a radioactive half-life of about 30 years and decays by beta decay either to stable barium - 137 or a meta- stable form of barium ( barium - 137m ). Nature of Decay Barium-137m is a product of a common fission product – Caesium – 137. The main gamma ray of Barium-137m is 661keV photon. As was written, atomic nuclei consist of protons and neutrons, which attract each other through the nuclear force, while protons repel each other via the electromagnetic force due to their positive charge.

Barium 137m decay

Half-life of Barium-137 m. Nuclear decay is a random process, yet it proceeds in a predictable fashion. To resolve this paradox, consider an everyday analogy. An unstable nucleus in a sample of radioactive material is like a popcorn kernel in a batch of popcorn that is being heated. When a kernel pops
