A. Half-Life of a Short-Lived Radioisotope Cesium-137 is a radioactive isotope with a half-life of 30.2 years. It undergoes decay to produce barium-137m, an unstable nuclear "isomer" that further decays to the stable barium-137 nucleus by emission: (5) The half-life of 137mBa is only 2.55 minutes.

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.

Since the half-life of 137”Ba is only 2.6 Its other emissions are negligible. In 0.944 of transformations, barium 137m ( radioactive half life 2.552 minutes) is produced. This decays by gamma emission in and an Associated Radionuclide. Radiation Energy (MeV). Isotope. Half-Life.

The Cesium nuclei have a half-life of 30 years and Cesium is always decaying, building up an equilibrium amount of Ba-137m. Ba-137m has a short half-life and quickly decays down to its stable ground state by the emission of a 0.662 MeV gamma ray.

The cesium atoms have a half-life of 30 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. The difference between these two times is your measured half life for Barium-137m. Mark the half life on your graph.

The Half-Life of Barium-137m 2 Estimated Time 1 hour Objective: Describe how the half-life of a short-lived radioactive substance can be determined. Background: The activity of a radioactive isotope is proportional to the quantity of isotope present. Activity is an extensive property.
