This is Ba137 which is a stable isotope of Barium. Cs137, 55, 82, 1149.293, 3.39 level the nuclide does not exist long enough for its mass to be measured.

Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and plutonium. This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles. 2016-02-18 The isotopic ratio of 135 Cs/ 137 Cs has been highlighted as a useful long-term tracer for radioactive contamination source identification since the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident.

3×10 -4 milligrams per liter Jefferson Lab, U.S. Department of Energy 3 History The name derives from the Latin caesius for "sky blue", which was the colour of the caesium line in the spectroscope. Since the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident in 2011, the activity ratio of 134 Cs/ 137 Cs has been widely used as a tracer for contamination source identification. However, because of the short half-life of 134 Cs (2.06 y), this tracer will become unavailable in the near future.

Only one isotope, 133 Cs, is stable. The longest-lived radioisotopes are 135 Cs with a half-life of 2.3 million years, 137 Cs with a half-life of 30.1671 years and 134 Cs with a half-life of 2.0652 years. All other isotopes have half-lives less than 2 weeks, most under an hour. 135 Cs/ 137 Cs atomic ratios of 0.341–0.351 were found in Japanese soil samples. Abstract For source identification, measurement of 135 Cs/ 137 Cs atomic ratio not only provides information apart from the detection of 134 Cs and 137 Cs, but it can also overcome the application limit that measurement of the 134 Cs/ 137 Cs ratio has due to the short half-life of 134 Cs (2.06 y).

This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles. Both Cs 137 and its Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
