The fleet of radioactive carbon C-14 in the atmosphere. Radioactive carbon, or carbon-14 (\(^{14}C\)), is an unstable, weak radioactive isotope of carbon used primarily to determine the age of organic materials less than 50,000 years old. Formed naturally in the upper atmosphere via cosmic rays, it has a half-life of roughly 5,730 years, decaying back into nitrogen-14 (\(^{14}N\)).
