The generator utilizes the beta decay of 137Cs: The parent isotope 137Cs beta decays with a half-life of 30.1 years to the metastable state of 137mBa.

The Cs/Ba-137m Isotope Generator is designed to demonstrate the properties of radioactive decay. This product is exempt from USNRC and State licensing and

The main gamma ray of Barium-137m is 661keV photon. As was written, atomic nuclei consist of protons and neutrons, which attract each other through the nuclear force, while protons repel each other via the electromagnetic force due to their positive charge. These two forces compete, leading to various Its decay product, barium-137m (the “m” means metastable) stabilizes itself by emitting an energetic gamma ray with a half-life of about 2.6 minutes. It is this decay product that makes cesium an external hazard (that is, a hazard without being taken into the body). 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. Because of their different chemical behavior, Cs and Ba can be readily separated and the half-life of the short-lived barium isotope can be followed directly. Half-life of Barium-137 m.

Barium 137m decay

Cesium-137 is significant because of its prevalence, relatively long half life (30 years), and its potential effects on human health. 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. Use our equipment to measure the half-life of a radioactive isotope, barium-137m!

Barium-137. Barium, isotope of mass 137.

The Equations Can Be Any Form Shown Below emitted from the barium decay product, Ba-137m, are a form of ionizing radiation that can pass through the human body, delivering doses to internal tissue and organs. People may also be exposed internally if they swallow or inhale cesium-137. Large amounts of cesium-137 were produced durin

The cesium atoms have a half-life of 30 years and is always decaying and building up an equilibrium amount of Ba-137m. Ba-137m has a half-life of only 2.55 minutes (153 seconds) and quickly decays down to 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 Ba-137m is said to be selectively "milked" from the generator that is sometimes called a "cow." The source of the Ba-137m is a mini generator or "cow." The Ba-137m is formed by the disintegration of Cs-137. The “m” in Ba-137m means that the nucleus of the newly formed Barium atom is in an excited state. The excited nucleus emits energy and becomes stable.
