Barium (Ba) 133 Radioactive Isotope Decay Calculator. Online radioactive decay calculator that allows you to find out the radioactivity decay in Barium (Ba) 133. Note: The calculation of radioactivity in minerals is based on certain assumptions.

Barium-137m is radioactive - it undergoes gamma decay. That is, the Barium-137m nucleus decays by emitting a high-energy photon. If Z is the atomic number of Barium-137m and A is the mass number of Barium-137m, what are the atomic number, Z', and mass number, A', of the daughter nucleus that remains after Barium-137m decays?

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.

People may also be exposed internally if they swallow or inhale cesium-137. Large amounts of cesium-137 were produced durin HB 01-19-10 Half-Life of Ba-137m 2 radioactive barium will reach an equilibrium amount in 4-5 barium half-lives. When needed for the experiment, the barium is ushed out of the source by an \eluting" solution. Elute is a verb that means to remove an adsorbate from an absorbent by means of a solvent. The life of 30 years. 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).
