These measurements are used in the subsequent calculation of the age of the sample. The accuracy of carbon dating relies on faulty assumptions, and is subject to human bias. Inhe wrote an article for the Anthropological Journal of Canada, in which stated: Both beta counting and AMS results have to be corrected for fractionation.

Also, archaeologists cannot use their hands to touch the samples or smoke near them.
