- Approximately 3.8394 × 10^-12 per secondThe decay constant for Carbon-14 is approximately 3.8394 × 10^-12 per second, corresponding to a half-life of 5,730 years123. Carbon-14 undergoes beta decay, emitting an electron and an electron antineutrino, resulting in the stable nuclide Nitrogen-1413. This property is used in radiocarbon dating to estimate the age of organic materials4.Learn more:✕This summary was generated using AI based on multiple online sources.
