Radiocarbon dating technique is primarily based on the radioactive decay of Carbon-14 isotope.Developed by a team of researchers under the leadership of Dr.
Thus by comparing the relative quantity of carbon -12 and carbon -14 in an organic matter excavated scientists can predict the age of the object (R. Where N is the current amount, N_o is the original amount, lambda is the proportionality constant for the growth rate (which is negative for decay), and t is the amount of time that has passed. Source: (Brain, 2014) The half-life of carbon-14 is 5730 years.
The method was taken from the detection techniques used in nuclear physics and adapted to the special requirements of low-level counting of the carbon gases.
A compilation made by W G Mook in 1983 lists 174 gas counters used in as counting gas.
Significance Desmond Clark (1979) opinions that if radio carbon dating technique were not discovered, (Clark, 1979:7). Exploratory analysis of the international radiocarbon cross- calibration data: consensus values and interlaboratory error.
According to Higham (1999) C14 method can be described as ‘the radio carbon revolution’ which has significantly impacted our understanding about evolution and also cultural emergence of human species.
This implies that it takes 5730 years for half of the 14C atoms in the organic matter to get decayed.
