Ba Ba Cs 56 55 137m 137 137 2.55 m The half-life of Barium-137m is approximately 153 seconds. 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.

After two half-lives have elapsed, only 1/4 of the 137 Ba nuclei will be in the 137 Ba* form, and 3/4 will have decayed to the ground state. After three half-lives, only 1/8 are 137 Ba*. 1954-03-01 extracted from the resin by this eluting solution. The cesium atoms have a half-life of 30 years and is always decaying and building up an equilibrium amount of Ba-137m.

This isotope of cesium is a emitter and 94.6% of the time decays to a metastable state of barium, 56Ba137m. This isotope of barium decays to the ground state by emitting a 0.662 MeV gamma ray photon.

The Cs-137 continually decays into Ba-137m. The metastable isotop Ba-137m arising 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. and an Associated Radionuclide.
