Barium 137m half life

Heretofore, various methods have been employed for the preparation of barium-137m generators. For example, J. J. Pinajian (J. Chem. Educ. 44, 212, 1967) adsorbed cesium-137 on zirconium phosphate and extracted barium-137m in 1M hydrochloric acid with a recovery of about 20 percent.

Sample was radioactive at the beginning of the experiment.

Radioactive Half-life of Barium-137m by Dr. 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. 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. lived decay product, barium-137m.

Do the division and you'll end up with the half-life, in seconds!Steve: The half-life of metastable barium-137 is listed as being 2.552 minutes, which is about 153 seconds.
