Otzi radiocarbon dating
The sample-context relationship is not always straightforward.Date of a sample pre-dates the context it is found.Labels attached to the packaging materials must not fade or rub off easily.Glass containers can be used when storing radiocarbon dating samples, but they are susceptible to breakage and can be impractical when dealing with large samples.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.Other labs accept waterlogged wood while others prefer them dry at submission.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.
Carbon 14 dating remains to be a powerful, dependable and widely applicable technique that is invaluable to archaeologists and other scientists.
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.
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.
