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.
During their use, some of the non-radioactive carbon-12 and carbon-13 isotopes in graphite get converted into radioactive 14 C by capturing neutrons. [12] When the graphite blocks are removed during station decommissioning, their induced radioactivity qualifies them as low-level waste requiring safe disposal.
Carbon-14 is a radioactive isotope of carbon, with a half-life of 5,730 years [28] [29] (which is very short compared with the above isotopes), and decays into nitrogen. [30] In other radiometric dating methods, the heavy parent isotopes were produced by nucleosynthesis in supernovas, meaning that any parent isotope with a short half-life ...
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby.
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon (14 C), a radioactive isotope of carbon. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.
Records show that from the 1940s through the 1960s, it was not uncommon for local hospitals, labs and other industrial operations to dispose barrels of tritium, carbon-14 and other similar waste ...
Radioactive graphite removed from nuclear reactors has been investigated as a source of electricity for low-power applications. This waste is rich in carbon-14, which emits electrons through beta decay, so it could potentially be used as the basis for a betavoltaic device. This concept is known as the diamond battery.
