This process is called The difference between these two times is your measured half life for Barium-137m. Mark the half life on your graph. Since your graph is plotted on regular (linear) graph paper, you will have to do a little bit of work to figure out where the second (later) activity is half the first. Follow the following steps if you need help figuring this out … BARIUM-137 isotope is used for studies of high-temperature superconductors; Barium-137 isotope is available to order from BuyIsotope.com in Barium-137 carbonate (BaCO3) chemical form.

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.
