Other potential contaminants include paper, cardboard, cotton wool, string and cigarette ash.3.

The proportion of carbon 14 in the sample examined provides an indication of the time elapsed since death of the sample’s source.Radiocarbon dating results are reported in uncalibrated years BP (Before Present), where BP is defined as AD 1950.The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon.When a living thing dies, it stops interacting with the biosphere, and the carbon 14 in it remains unaffected by the biosphere but will naturally undergo decay.Radiocarbon dating has been around for more than 50 years and has revolutionized archaeology.

Carbon 14 dating remains to be a powerful, dependable and widely applicable technique that is invaluable to archaeologists and other scientists.Decay of carbon 14 takes thousands of years, and it is this wonder of nature that forms the basis of radiocarbon dating and made this carbon 14 analysis a powerful tool in revealing the past.The process of radiocarbon dating starts with the analysis of the carbon 14 left in a sample.Aluminum containers with screw caps are safe, but it is still best to consult the radiocarbon laboratory for the best containers of carbon dating samples.4.Errors and calibration It is recommended that archaeologists, or any client in general, ask the laboratory if results have systematic or random errors.Sample type, size and packing Laboratories have limitations in terms of the samples they can process for radiocarbon dating. Laboratories must also be consulted as to the required amount of sample that they ideally like to process as well as their preference with certain samples for carbon dating.
