Origin of carbon dating
Other labs accept waterlogged wood while others prefer them dry at submission.Contaminants must not be introduced to the samples during collection and storing.Hydrocarbons, glue, biocides, polyethylene glycol, or polyvinylacetate must not come in contact with samples for radiocarbon dating.Other potential contaminants include paper, cardboard, cotton wool, string, and cigarette ash.The process of radiocarbon dating starts with the analysis of the carbon 14 left in a sample.
Radiocarbon dating has been around for more than 50 years and has revolutionized archaeology.
An archaeologist must also make sure that only the useful series of samples are collected and processed for carbon dating and not every organic material found in the excavation site.
It is important that the radiocarbon scientists and archaeologists agree on the sampling strategy before starting the excavation so time, effort, and resources will not be wasted and meaningful result will be produced after the carbon dating process.
Radiocarbon dating results are reported in uncalibrated years BP (Before Present), where BP is defined as AD 1950.
Calibration is then done to convert BP years into calendar years.
