Possible errors in carbon dating dating wives captions

Second, radiocarbon dating becomes more difficult, and less accurate, as the sample gets older.

The bodies of living things generally have concentrations of the isotope carbon-14, also known as radiocarbon, identical to concentrations in the atmosphere.

Likewise, different living things absorb or reject carbon-14 at different rates.

This is perhaps the greatest point of potential error, as assumptions about dating can lead to circular reasoning, or choosing confirming results, rather than accepting a “wrong” date.Even then, a large proportion of radiocarbon dating tests return inconsistent, or even incoherent, results, even for tests done on the same sample.The explanation given for these outliers is usually “contamination.” Inconsistent results are another reason why multiple samples, multiples tests, and various parallel methods are used to date objects.Radiocarbon dating can’t tell the difference between wood that was cut and immediately used for the spear, and wood that was cut years before being re-used for that purpose.Nor can it tell if a much older spearhead was attached to a brand-new shaft.Most archaeological items can’t be directly carbon dated, so their dating is based on testing done on nearby objects or materials.
