Isotopes of Sodium
Notable Isotopes show graph
22Na [11 neutrons]
Abundance: synthetic
Half life: 2.602 years [ beta+ ]
Decay Energy: 0.546 MeV
Decays to 22Ne.
Half life: 2.602 years [ Electron Capture ]
Decay Energy: ? MeV
Decays to 22Ne.
Half life: 2.602 years [ Gamma Radiation ]
Decay Energy: 1.2745 MeV
Decays to ?.
23Na [12 neutrons]
Abundance: 100%
Stable with 12 neutrons
Acute neutron radiation exposure (e.g., from a nuclear criticality accident) converts some of the stable 23Na in human blood plasma to 24Na. By measuring the concentration of this isotope, the neutron radiation dosage to the victim can be computed.
