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: 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.

1. Peter norberg sundsvall

Record this value in the table. 12. Are your values of t1/2 (measured and calculated) consistent with the accepted value of approximately 2.552 minutes for the half-life of barium-137? 13. What fraction of the initial activity of your barium sample would remain 137m, the metastable state that is a product of Cs -137 radioactive decay. The half-life is the amount of time it takes N radioactive nuclei to decay to half of the original radioactive nuclei. The isotope generators that we are using contain up to 10 μCi (370 kBq) of Cs-137 (± 20%) bound on a special ion exchange medium and can produce the Now, half-lives can range from billions of years to a tiny fraction of a second.

HALF-LIFE OF BARIUM-137M Introduction: One of the characteristics often used to describe radioisotopes is half-life. Half-life is Now, half-lives can range from billions of years to a tiny fraction of a second.

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. Please contact us via request a Barium-137 quote BuyIsotope.com to order Barium-137 isotope, to get Barium-137 price and to buy Barium-137 isotope. relatively long half life (30 years), and its potential effects on human health. Cesium-137 emits beta particles as it decays to the barium isotope, Ba-137m (half life = 2.6 minutes).

Decay Mode: β¯. Half-Life: (11000 ± 90) d. [2].

It undergoes beta decay into barium-137 The half-life for this disintegration is approximately 30 years. 64 g sample of Cs-137 is analyzed every 30 years for 150 year time period.

An unstable nucleus in a sample of radioactive material is like a popcorn kernel in a batch of popcorn that … 2019-10-07 View Half-Life-of-Barium-137m.doc from BMT B-143 at U.E.T Taxila. HALF-LIFE OF BARIUM-137M Introduction: One of the characteristics often used to describe radioisotopes is half-life. Half-life is Now, half-lives can range from billions of years to a tiny fraction of a second. Happily, the half-life of metastable barium-137 isn't too long and isn't too short. It's perfect for doing a half-life experiment like this within a reasonable amount of time.
