Cesium-137 has a radioactive half-life of about 30 years and decays by beta decay either to stable barium-137 or a meta-stable form of barium (barium-137m). The metastable isotope ( barium -137m) is rapidly converted to stable barium-137 (half-life of about 2 minutes) accompanied by gamma ray emission whose energy is 0.662 MeV. The isogenerator contains cesium-137, which decays to produce barium-137. The newly made barium nucleus is initially in a long-lived excited state, which eventually decays by emitting a gamma photon and becomes stable. By measuring the decay of a sample of barium-137, you will be able to calculate its half-life. Write a balanced nuclear equation for the following: The nuclide cesium-137 undergoes beta decay to form barium-137. Joanna: We're finally ready to calculate the half-life of metastable barium-137 using the data that you collected earlier.

The newly made barium nucleus is initially in a long-lived excited state, which eventually decays by emitting a gamma photon and becomes stable. By measuring the decay of a sample of barium-137, you will be able to calculate its half-life.

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. Don't panic. As far as equations go in physics, this one isn't too bad. Cesium-137 beta-decays to Barium-137m write a nuclear equation for the alpha decay of 231 91 Pa i got 231 91 Pa ----> 4 2 He THIS is Chemistry. 1 Educator answer. Online radioactive decay calculator that allows you to find out the radioactivity decay in Cesium (Cs) 137.

Barium-114 is predicted to undergo cluster decay, emitting a nucleus of stable 12 C to produce 102 Sn. After one half-life has elapsed, only 1/2 of the137Banuclei remain in the 137Ba* form, and 1/2 will have decayedto the ground state. After two half-lives have elapsed, only 1/4of the137Banuclei will be in the 137Ba* form, and 3/4 will havedecayedto the ground state. After three half-lives, only 1/8 are 137Ba*.

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. Barium-114 is predicted to undergo cluster decay, emitting a nucleus of stable 12 C to produce 102 Sn. After one half-life has elapsed, only 1/2 of the137Banuclei remain in the 137Ba* form, and 1/2 will have decayedto the ground state. After two half-lives have elapsed, only 1/4of the137Banuclei will be in the 137Ba* form, and 3/4 will havedecayedto the ground state. After three half-lives, only 1/8 are 137Ba*. This further decays by gamma emission (662 keV) with a half-life of 2.6 min. to the stable Ba-137 element. During elution, the Ba-137m is selectively “milked” from the generator, leaving behind the Cs-137 parent.
