Carbon-14 undergoes beta decay: . 14 6 C → 14 7 N + e − + ν e + 0.156.5 MeV. By emitting an electron and an electron antineutrino, one of the neutrons in carbon-14 decays to a proton and the carbon-14 (half-life of 5700 ± 30 years [1]) decays into the stable (non-radioactive) isotope nitrogen-14.
An example of electron emission (β − decay) is the decay of carbon-14 into nitrogen-14 with a half-life of about 5,730 years: 14 6 C → 14 7 N + e − + ν e. In this form of decay, the original element becomes a new chemical element in a process known as nuclear transmutation.
The equation for the radioactive decay of 14 C is: [17] 14 6 C → 14 7 N + e − + ν e. By emitting a beta particle (an electron, e −) and an electron antineutrino (ν e), one of the neutrons in the 14 C nucleus changes to a proton and the 14 C nucleus reverts to the stable (non-radioactive) isotope 14 N.

14 C undergoes beta decay, in which it emits a low-energy beta particle to become Nitrogen-14, which is stable (not radioactive). [9] 14 6 C → 14 7 N + 0 −1 β. These beta particles, having an average energy of 50 keV, undergo inelastic collisions with other carbon atoms, thus creating electron-hole pairs which then contribute to an ...
Carbon-14 has a half-life of 5700(30) years [27] and a decay rate of 14 disintegrations per minute (dpm) per gram of natural carbon. If an artifact is found to have radioactivity of 4 dpm per gram of its present C, we can find the approximate age of the object using the above equation:
A common example of an unstable nuclide is carbon-14 that decays by beta decay into nitrogen-14 with a half-life of about 5,730 years: 14 6 C → 14 7 N + e − + ν e. In this form of decay, the original element becomes a new chemical element in a process known as nuclear transmutation and a beta particle and an electron antineutrino are emitted.
Most fermions decay by a weak interaction over time. Such decay makes radiocarbon dating possible, as carbon-14 decays through the weak interaction to nitrogen-14. It can also create radioluminescence, commonly used in tritium luminescence, and in the related field of betavoltaics [4] (but not similar to radium luminescence).
Tritium is a low-energy beta emitter commonly used as a radiotracer in research and in traser [check spelling] self-powered lightings.The half-life of tritium is 12.3 years. The electrons from beta emission from tritium are so low in energy (average decay energy 5.7 keV) that a Geiger counter cannot be used to detect the
