Ex: The recent study of archeological remains, particularly radiocarbon research, indicates that India has a very rich prehistory going back into the late Pleistocene period.

* radiocarbon date = datar por radiocarbono, datar por carbono 14
* radiocarbon dating = datación por radiocarbono, datación por carbono 14
Ex: The paper that is to be examined is simply sandwiched between a sheet of Perspex impregnated with carbon-14 and an unexposed photographic film, and left in the dark for a few hours.
Ex: One of these contained an inhumation which was radiocarbon dated to the Iron Age.
Definition
Wikipedia
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 materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on February 27, 1940, by Martin Kamen and Sam Ruben at the University of California Radiation Laboratory in Berkeley, California. Its existence had been suggested by Franz Kurie in 1934.
There are three naturally occurring isotopes of carbon on Earth: carbon-12 (12
C), which makes up 99% of all carbon on Earth; carbon-13 (13
C), which makes up 1%; and carbon-14 (14
C), which occurs in trace amounts, making up about 1 or 1.5 atoms per 1012 atoms of carbon in the atmosphere. Carbon-12 and carbon-13 are both stable, while carbon-14 is unstable and has a half-life of 5700±30 years. Carbon-14 has a maximum specific activity of 62.5 mCi/mmol (2.31 GBq/mmol), or 164.9 GBq/g. Carbon-14 decays into nitrogen-14 (14
N) through beta decay. A gram of carbon containing 1 atom of carbon-14 per 1012 atoms will emit ~0.2 beta particles per second. The primary natural source of carbon-14 on Earth is cosmic ray action on nitrogen in the atmosphere, and it is therefore a cosmogenic nuclide. However, open-air nuclear testing between 1955 and 1980 contributed to this pool.
The different isotopes of carbon do not differ appreciably in their chemical properties. This resemblance is used in chemical and biological research, in a technique called carbon labeling: carbon-14 atoms can be used to replace nonradioactive carbon, in order to trace chemical and biochemical reactions involving carbon atoms from any given organic compound.
