lived decay product, barium-137m. The latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium. Cesium-137 is significant because of its prevalence, relatively long half life (30 years), and its potential effects on human health. Cesium-137 emits beta particles as it decays to the barium isotope, Ba-137m (half life = 2.6 minutes).

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. Regeneration of the Ba-137m occurs as the Cs-137 continues to decay, re-establishing equilibrium in less than 1 hour.

Cesium-137 is significant because of its prevalence, relatively long half life (30 years), and its potential effects on human health. Cesium-137 emits beta particles as it decays to the barium isotope, Ba-137m (half life = 2.6 minutes).

From the data you will determine the decay constant and the half-life of the sample. 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.

The latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium. The time required for a radioactive substance to lose 50 percent of its radioactivity by decay is known as the half-life. Cesium-137 is significant because of Cesium-137* Isotope Decays Into Barium-137* Isotope.

2014-09-13 · A Cs-137/Ba-137m isotope generator is used to demonstrate the properties of radioactive decay. In this experiment, we investigate and verify the random behavior of radioactive decay and determine the half-life of a radioactive isotope. The half-life of a radioisotope is measured in this experiment. The purpose of this experiment is to determine the half-life of Ba-137m by using several methods
