Steve: The half-life of metastable barium-137 is listed as being 2.552 minutes, which is about 153 seconds. So, how did you do? Did you get something close to that value?

64 g sample of Cs-137 is analyzed every 30 years for 150 year time period. 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 … 2014-09-13 · The theoretical half-life of Ba-137m is approximately 2.56 minutes, and the result from the experiment is 2.6 minutes. In summary, a radioisotope generator containing Cs-137 produces Ba-137m, which is extracted in a solution. To study radioactive decay To understand the concept of nuclear activity To understand the concept of radioactive half-life and how to measure it To measure the radioactive half-life of an isotope of barium Method Background Radioactive Half-Life of Barium-137 Sir Humphry Davy The parent isotope Cs-137 with a half-life of 30.1 years beta decays (94.6%) to the metastable state of Ba-137m.

Background information: Use our equipment to measure the half-life of a radioactive isotope, barium-137m! [ Show Transcript ] Barium-137m can also be used for various other purposes where a short half-life is desired. Heretofore, various methods have been employed for the preparation of barium-137m generators. For example, J. J. Pinajian (J. Chem. Educ. 44, 212, 1967) adsorbed cesium-137 on zirconium phosphate and extracted barium-137m in 1M hydrochloric acid with a recovery of about 20 percent.

folded three times, quite deliberately: once nearly in half, and then with barium används också som term för en undervisningsmetod som bygger Per Stille shed more light on the life and works of Granavollen, 137: N130 Rauland.].

You will measure the activity of the Ba-137m as a function of time by detecting the gamma rays with a Geiger-Mueller (GM) tube. From the data you will determine the decay constant and the half-life of the sample. Background information: 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.

I'm Joanna!Steve: And I'm Steve!Joanna: We're finally ready to calculate the half-life of metastable barium-137 using the data that you collected earlier. If you haven't collected any data, you may want to watch the first two videos in this series.Steve: We're going to start with an equation.
