We have negotiated special rates with reputable radiocarbon laboratories which allows us to provide exceptional value for money.For more details please contact one of our senior archaeologists using this link.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.The raw 'uncalibrated' radiocarbon ages are given in radiocarbon years before the present day (BP) but these do not equate directly to actual calendar years due to variations in atmospheric carbon over time.
In this second article he describes the phenomenon of radioactive decay, which also obeys an exponential law, and explains how this information allows us to carbon-date artefacts such as the Dead Sea Scrolls.
After the plants die or are consumed by other organisms the 14C fraction declines at a fixed exponential rate due to the radioactive decay of 14C.
Comparing the remaining 14C fraction of a sample to that expected from atmospheric 14C allows the age of the sample to be estimated.
