Large amounts of cesium-137 were produced durin Measurement of Half-Life Ba-137m Kyle Hung (kh36368) PHY 353L Modern Laboratory Department of Physics The University of Texas at Austin September 18, 2019 Abstract The reason for the observation of the radioactive decay of Barium-137m is the calculation of the isotope’s half-life. Using a photomultiplier tube, we were able to count the instances of gamma radiation coming from a generated Analysis of graph #1: Find the experimental decay constant for Barium-137m from the slope of your graph.

Barium 137m decay

The generator utilizes the beta decay of 137Cs: The parent isotope 137Cs beta decays with a half-life of 30.1 years to the metastable state of 137mBa.

Anon, Jahrb. Pharm., 45, 44, Apoth. Ztg., 25, 894., C.A.. 6, 1656 (1912).

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.

It is then measured for three additional one-minute periods, separated by two minutes. About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m (137m Ba, Ba-137m). The remainder directly populates the ground state of barium-137, which is stable. Metastable barium has a half-life of about 153 seconds, and is responsible for all of the gamma ray emissions in samples of caesium-137. Molecular Formula. Ba. Synonyms. Barium-137.

Isotope activity decays to a relatively short-lived radioactive daughter. parent does not decay appreciablyduring the course of. 23 Jul 2003 of nuclide to decay, i.e., be converted into another species. Write the nuclear equation for the transformation of Ba-137m to Ba-137. 3. 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) .
