You will be given a geiger counter and a sample which contains a small number of barium (Ba) ions (more specifically, the isotope 137Ba) that have been created  

Classify and describe, in equation form, types of chemical and nuclear reactions. Explain how radioactive isotopes that are subject to decay … Regeneration of the Ba-137m occurs as the Cs-137 continues to decay, re-establishing equilibrium in less than 1 hour. Approximately 30 minutes after elution, the residual activity of the Ba-137m sample has decayed to less than one thousandth of its initial activity, making it safe for disposal. Barium-137 is stable in the ground state, but it has an isomeric state which decays 100% of the time through internal conversion.

In: Nature  It has a half-life of about 30.17 years, and decays by beta emission to a metastable nuclear isomer of barium-137: barium-137m (137mBa, Ba-137m). ( About 95  Barium-137m is a product of a common fission product – Caesium – 137. The main gamma ray of Barium-137m is 661keV photon. As was written, atomic nuclei  It has a half-life of 30.23 years, and decays by pure beta decay to a metastable nuclear isomer of barium-137 (Ba-137m). Barium-137m has a half-life of 2.55  2020年6月26日 For the electromagnetic nuclear interaction, the observation of the competitive double-γ decay from 137mBa has opened up the nuclear  The Cs-137 continually decays into Ba-137m.

Radioactive decay and the half-life concept can be shown by three methods, each of As the radon decays, so does the cur- Radioactive decay of Ba- 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 Ba-137m has a half-life of about 1seconds, and is responsible for all of the emissions of gamma rays in samples of caesium-137. Each generator contains µCi of Cs-137.

1 Jun 2017 The slope calculation MUST be on the graph if it is a shared graph. Analysis of graph #1: Find the experimental decay constant for Barium-137m 

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 ). Nature of Decay Barium-137m is a product of a common fission product – Caesium – 137.
