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 sample-context relationship is not always straightforward.

Date of a sample pre-dates the context it is found.

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.

Calibration is then done to convert BP years into calendar years.

Samples must be stored in packaging materials that will protect them during transport and even during prolonged storage.History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past.Historians can tell what cultures thrived in different regions and when they disintegrated.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.

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.
