Professional radiocarbon dating

Archaeological Research Services Ltd in collaboration with English Heritage have been at the forefront of recent developments including the use of Bayesian probability modelling to date the internationally renowned Mesolithic house site at Howick.

When isotopes are to be designated specifically, the chemical symbol is expanded to identify the mass (for example, C is not stable.

Because atmospheric carbon 14 arises at about the same rate that the atom decays, Earth's levels of carbon 14 have remained fairly constant.

Once an organism is dead, however, no new carbon is actively absorbed by its tissues, and its carbon 14 gradually decays.

We have negotiated special rates with reputable radiocarbon laboratories which allows us to provide exceptional value for money.

Radiocarbon dating is the process of measuring the amount of carbon-14 isotope remaining in an organic material and from this measurement the age of the sample can be calculated.

Carbon-14 (14C) is incorporated into plants when they photosynthesize carbon dioxide from the atmosphere.

They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14." If two atoms have equal numbers of protons but differing numbers of neutrons, one is said to be an "isotope" of the other.
