Radiocarbon dating is achieved by two methods the traditional beta-counting method is based on the detection of radioactive decay of the radiocarbon ( 14 c) atoms the ams (accelerator mass spectrometry) method is based on the detection of mass of 14 c atoms in the sample (and therefore its ratio of 14 c to 12 c. Radiocarbon forms in upper atmosphere: decays everywhere: l ½ = 5730 yr vocabulary isotope parent isotope daughter isotope nuclear decay half-life early ideas basic physical model (1939) production high in upper atmosphere as 14co2 fixed in the biosphere by photosynthesis equilibrium between atmosphere and organisms no. Radiocarbon dating is a radiometric method that uses the naturally occurring isotope carbon-14 to determine the age of carbonaceous materials up to ca 60,000 years within archaeology it is considered an absolute dating technique the technique was discovered by willard frank libby and his colleagues in 1949.

Carbon-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.

Basics of radiocarbon dating the term “radiocarbon” is commonly used to denote 14c, an isotope of carbon which is radioactive with a half-life of about 5730 years 14c is produced by cosmic rays in the stratosphere and upper troposphere.

Carbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere, taking in carbon dioxide from the air for photosynthesis cosmic ray protons blast nuclei in the upper atmosphere, producing neutrons which. Carbon - dating has therefore become an important tool for archaeologists and anthropologists radiocarbon or c -14, is a radioactive isotope of carbon it is used to determine the age of fossils and other ancient organic matters.
