Radiocarbon dating proceedings of the ninth international conference intimacy dating questions
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.
This implies that it takes 5730 years for half of the 14C atoms in the organic matter to get decayed.
The Method of Carbon-14 Technique Archaeologists rely on the various radiometric dating techniques- based on the radioactive properties of unstable chemical atoms to determine the age of the materials. In the biosphere carbon-14 is created by the collision of a neutron, exited by the cosmic ray collides with a nitrogen atom.
Researchers from the field of Physics have discovered that radioactive molecules are unstable and they undergo decay to attain a stable structure at a specific rate which is directly determined by the atomic number and mass of the decaying atom (Polach, H. The isotope of carbon thus produced is radioactive and it will undergo decay at a constant rate (Berger and H. The carbon isotope is also absorbed during photosynthesis by plants and reaches animal body when they consume plant parts.

Conclusion Despite all the limitations radio carbon dating will remain as a significant tool for archaeologist around the globe to compare and understand the evolution of human culture and civilization. Thus undoubtedly radiocarbon dating remains one of the significant tools for the archaeologist to explain the evolution and cultural emergence in a more accurate manner.
Advancements in this field like accelerator techniques of carbon-14 dating (C.
Developed by a team of researchers under the leadership of Dr.
Willard Libby, this technique had revolutionized the way the archaeological advancements are made in learning about the past civilization and cultures, changes occurred in the earth and in its climate.
