Molar Mass, 132.91 gmol-1 Stable Isotopes, 133Cs Caesium-137 is a radioisotope commonly used as a gamma-emitter in industrial . Cesium By Abby Grimes. Symbol: Cs Atomic number: 55. Atomic mass: 132.905 In 1987, a Brazilian city became contaminated with radiative cesium-137.

It is very reactive. It is highly explosive when exposed to water. Determination of low-level 135 Cs and 135 Cs/ 137 Cs atomic ratios in large volume of seawater by chemical separation coupled with triple-quadrupole inductively coupled plasma mass spectrometry measurement for its oceanographic applications. For Cs-137 – 1.3 E16 Bq = 350,000 curies. Cs-137 has a much longer half life than I-131; each gram only contains about 88 curies (0.0114 grams Cs-137/curie) Therefore the total mass of Cs-137 released into the atmosphere was” 350,000 curies x 0.0114 gram Cs-137/curie = 3980 grams (4 kg) – of Cs-137. Cs-137 from nuclear accidents or atomic bomb explosions cannot be seen and will be present in dust and debris from fallout. How can I be exposed to Cs-137?

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.

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. Of the remaining 500 cesium-137 atoms, 250 will be similarly transformed over the succeeding 30-year period. Barium-137 has a half-life of 2.55 minutes.

Räkna med atommassenheten 127 Räkna med substansmängd 129 En av de radioaktiva klyvningsprodukterna som ingår i använt kärnbränsle är cesium137. (Grundämnet cesium betecknas Cs och har atomnummer 55.)

The atomic masses of these isotopes range from 112 to 151. Only one isotope, 133Cs, is stable. The longest-lived radioisotopes are 135Cs with a half-life of 2.3 million years, 137Cs with a half-life of 30.1671 years and 134Cs with a half-life of 2.0652 years. All other isotopes have half-lives less than 2 weeks, most under an hour. Beginning in 1945 with the commencement of nuclea Common Names: Cesium-137 Chemical Symbol: Cs-137 or 137Cs Atomic Number: 55 Mass Number: 137 (82 neutrons) Chemical Form: Cesium chloride Physical Form: Atomic Weight: 136.907089473: Abundance: None: Mass Excess-86.545599MeV: Binding Energy: 8.388956MeV: Magnetic Moment: 2.8413 μ: Quadrupole Moment: 0.051 It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Cs-137 (Caesium It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Cs-137 (Caesium, atomic number Z = 55, mass number A = 137). Caesium-137 (atomic mass 137) is a heavier, radioactive isotope of Caesium (Cs) whose most stable form is Cs-133. Silvery white, soft, and malleable, Cs-137 is one of the very few metals that exist in liquid form at room temperature.
