Carbon-14, the longest-lived radioactive isotope of carbon, whose decay allows the accurate dating of archaeological artifacts from 500 to 50,000 years old. Carbon-14 has a half-life of 5,730 years.

Radioactive Decay Carbon-14 undergoes beta decay with emission of an electron and an electron antineutrino: 14 C → 14 N + e - + ve + 156.476 keV. The decay product is the stable nuclide …

Carbon-14 is a commonly used radionuclide with a half-life of 5,730 years, emitting only beta particles with a maximum energy of 0.156 MeV (Million Electron Volts) and an average energy of 0.049 MeV. …

Smear surveys are required. 4. Segregate waste to H3 and C14 only. Assume all waste areas are contaminated. 5. Limit soluble waste to the sewer to less than 1000 μCi/day per lab. • Delacroix, D., …
