44, 212, 1967) adsorbed cesium-137 on zirconium phosphate and extracted barium-137m in 1M hydrochloric acid with a recovery of about 20 percent. List of Barium Isotopes and Barium Applications: Barium-130 isotope (Ba-130 isotope, 130Ba isotope). BARIUM-130 isotope is used for Barium-131 (Ba-131 isotope, 131Ba isotope) positron-emitting radionuclide (radioisotope) production (can be used in life science for healthcare and medical applications and pharmaceuticals industries); 2015-09-16 In this lab activity you will be measuring the half-life of a radioactive isotope, barium-137m or meta-stable barium-137. Introduction: This isotope of barium is similar to a regular, stable Ba-137 isotope, but with too much energy remaining in the nucleus from previous decay steps. Lab 13 Half-life and Radioactive Waste Storage Yijia Gao Physics 1001W, TA: Juan Tigre Lazo Abstract In this lab, Cs-137/Ba-137m Isotope was used to demonstrate the properties of radioactive decay.
