The purpose of this experiment is to measure the half-life of barium-137 When the 137mBa decays into the ground state of 137Ba, it emits a gamma ray.
By measuring the decay of a sample of barium-137, you will be able to calculate its half-life. Follow all local procedures for handling radioactive materials. Follow
2020 — After 137Cs and 90Sr have decayed to low levels, the bulk of radioactivity from spent fuel come not from fission products but actinides, notably plutonium-239 (half-life 24 ka), plutonium-240 (6.56 25 Barium-138, 139, 140 Life of.

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.

In the following videos, we collected a sample of the unstable Barium-137 and measured the energy emitted ( γ \gamma γ) as it goes from the excited state to a
Purpose: Measure the half-life of Ba 137, approximately 156 seconds. Description: The 660 keV gamma ray from a Cesium 137 source is actually from its beta decay daughter, Barium 137.
