What does radiocarbon dating mean in history
Calibration is then done to convert BP years into calendar years.
This information is then related to true historical dates.
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.
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.
It must be stressed that archaeologists need to interact with radiocarbon laboratories first before excavation due to several factors.1.
Hydrocarbons, glue, biocides, polyethylene glycol or polyvinyl acetate (PVA) must not come in contact with samples for radiocarbon dating.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.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.
