Carbon-14, C-14, 14 C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons. Its presence in organic matter is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.

2023年10月20日 · Carbon-14 dating works by comparing the ratio of carbon-12 to carbon-14 in a sample to that in a living organism, allowing for the determination of the age of formerly living things fairly precisely.

2025年2月20日 · 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.

2025年3月13日 · Carbon-14 dating, method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14). Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere. Learn more about carbon-14 dating in …

Radiocarbon dating, or carbon-14 dating, is a scientific method that can accurately determine the age of organic materials as old as approximately 60,000 years. First developed in the late 1940s at the University of Chicago by Willard Libby, the technique is …

Carbon-14 is a radioisotope of the chemical element carbon, which has 8 neutrons in its atomic nucleus in addition to the element-specific 6 protons; the sum of the number of these atomic nucleus building blocks results in a mass number of 14.

Carbon-14 is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. C-14 dating is only applicable to organic and some inorganic materials (not applicable to metals).

Carbon-14. The only cosmogenic radionuclide to make a significant contribution to the internal exposure of humans is carbon-14. Radioactive carbon-14 has a half-life of 5730 years and undergoes β− decay, where the neutron is converted into a proton, an electron, and an electron antineutrino: Beta-decay of C-14 nucleus.

Dating - Carbon-14, Cosmogenic, Geochronology: The occurrence of natural radioactive carbon in the atmosphere provides a unique opportunity to date organic materials as old as roughly 60,000 years. Unlike most isotopic dating methods, the conventional carbon-14 dating technique is not based on counting daughter isotopes.

Carbon-14 dating is a fundamental method widely used in various scientific fields to determine the age of organic materials. This technique is essential for researchers, archaeologists, geologists, and environmental scientists when it comes to dating artifacts and understanding historical timelines. The significance of this dating method is not ...
