Uranium 235 + neutron = barium 144 + krypton 90 + 2 fast neutrons + Half-Life and Radioactive Decay - video with english and swedish subtitles.
Different references will give slightly different half-life values. Instruct the students in how to find half-life from a graph. Since Ba-137m has a short half-life, it only takes 30 minutes after a sample is acquired for the residual activity in the solution to essentially disappear. However, should a spill occur, wipe up any liquid and wash any exposed skin thoroughly with soap and water. A value for the half-life of barium-137m could be estimated from their data; it appeared to be about 2.52 min, compared with the 2.60 min previously measured by Mitchell and Peacock2. 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. decays to the ground state by emitting a 0.662 MeV gamma ray photon.

Did you get something close to that value? kBq) of Cs-137 (± 20%) bound on a special ion exchange medium and can produce the short lived isotope, Ba-137m (half-life: 2.6 minutes). Using an eluting solution (which is forced through the isotope exchange column using a syringe) the Ba-137 is selectively extracted from the ion exchange medium leaving only the Cs-137. This process is called The difference between these two times is your measured half life for Barium-137m.
People may be exposed externally to gamma radiation emitted by cesium-137 decay products. If very high doses
Ba-137m has a half-life of about 1seconds, and is responsible for all of the emissions of gamma rays in samples of caesium-137. Each generator contains µCi of Cs-137.
