to estimate the age of an organism by tracking the decay of the isotope carbon-14. Also called carbon-dating.

An absolute dating technique used to determine the age of organic materials less than 50,000 years old.  Age is determined by examining the loss of the unstable carbon-14 isotpe, which is absorbed by [..]

A technique for estimating the age of an object by measuring the amounts of various radioisotopes in it.

a method of dating material that contains the element carbon. The method uses isotopes of carbon, and can determine the age of materials as old as 70,000 years.

commonly known as carbon dating; a method for determining the age of carbon-bearing materials less than c. 60,000 years old, using the concentration of 14C calibrated against atmospheric 14C

The age of organic material determined by the amounts of carbon isotopes 12, 13 and 14. The ratio of 12 to 14 is about the same in all living things but when a plant or animal dies, no more carbon is [..]

A dating method measuring the percentage of radioactive carbon-14 in organic material such as charcoal or bone. It can be used to date materials up to about 40,000 years old.

A process that provides absolute dates by counting the radioactive decay of carbon in the remains of once living plants and animals (i.e., charcoal, wood, bone, shell).

an absolute dating method based on the radioactive decay of Carbon-14 contained in organic materials.

a radiometric method of dating organic material that is based on the rate that unstable radioactive carbon-14 atoms, which are present in all living things (humans, trees, etc.), decay into carbon-12 [..]

An absolute dating method that measures the decay of the radioactive isotope of carbom (14C

Establishing the relative age of various materials with the use of carbon-14. This involves measuring the amount of 14C and of 12C and comparing the measured ratio to the one established by the produc [..]

A dating technique based on the characteristic of carbon-14 (14C, a radioactive isotope) whose abundance ratio is constant in living organisms but decreases at a constant rate after their death.

A method to ascertain the actual age of an organic object (bone, charcoal, seeds, etc) based on the relative ratios of carbon 14 to non-radioactive isotopes of carbon at the time of the analysis.

A common method of dating organic material.

A technique for determining the absolute date of organic matter based on the fact that all living organisms contain a small but constant proportion of the radioactive isotope of carbon (C14)
