Isotopes of Chlorine
Notable Isotopes
35Cl [18 neutrons]
Abundance: 75.77%
Stable with 18 neutrons
36Cl [19 neutrons]
Abundance: synthetic
Half life: 3.01 x 105 years [ beta- ]
Decay Energy: 0.709MeV
Decays to 36Ar.
Half life: 3.01 x 105 years [ Electron Capture ]
Decay Energy: unknownMeV
Decays to 36S.
36Cl is produced in the atmosphere by spallation of 36Ar by interactions with cosmic ray protons.
Large amounts of 36Cl were produced by irradiation of seawater during atmospheric detonations of nuclear weapons between 1952 and 1958.
37Cl [20 neutrons]
Abundance: 24.23%
Stable with 20 neutrons
