When did radiocarbon dating begin
Carbon-14 has a half-life of 5,730 ± 40 years—, half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.The carbon-14 method was developed by the American physicist Willard F. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.
Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.
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.
The sample-context relationship is not always straightforward.
Date of a sample pre-dates the context it is found.
