Calibrated vs uncalibrated carbon dating
An uncalibrated dating using the Libby figure could be improved by multiplying by the ratio of these numbers (approximately 1.03), but this is usually unnecessary since the adjustment is included in modern calibration curves.
Additional error is likely to arise from the nature and collection of the sample itself, e.g., a tree may accumulate carbon over a significant period of time.is a radiometric dating method that uses the naturally occurring isotope carbon-14 to determine the age of carbonaceous materials up to ca. Within archaeology it is considered an absolute dating technique.The technique was discovered by Willard Frank Libby and his colleagues in 1949.Such wood, turned into an artifact some time after the death of the tree, will reflect the date of the carbon in the wood. This limit is encountered when the radioactivity of the residual 14C in a sample is too low to be distinguished from the background radiation.The K-Ar and uranium decay series are used in dating older objects (see Radiometric dating).
