It has a radio half-life (T 1/2) of 5,730 years and is a low energy beta emitter with a radioactive range in air of ten inches.It is produced currently at a fairly constant rate in the upper atmosphere through the action of cosmic radiation on Nitrogen-14.The science of archaeology has undeniably enriched mankind’s history and has helped to quench the quest to understand our past cultures in a better way.Understanding the age and period of existence of the excavated fossils and other organic objects will help the archaeologist to unravel human history and evolution in a scrupulous manner (Taylor 24).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.Taylor (1987) suggests C-14 technique as one of the most significant discoveries of 20thcentury that touches the realms of many disciplines including archaeology.When an organism is dead the intake of the carbon-14 stops and in a 5730 year time period, half of the amount of carbon-14 present in the organic matter would have undergone beta decay to form stable Nitrogen-14. The burning of a small piece of the excavated organic matter and measuring the electrons emitted during the process by the decaying carbon-14 by radiation counters enable to quantify the amount of carbon -14 present in the material. “Why Is Radiocarbon Dating Important to Archaeology.” California State Parks.

Otherwise archaeologists had to resort t to the method of relative dating where by comparing with stratigraphically close objects [objects which are buried at the same depth will be approximately of the same era.] clue regarding the time period and historical styles were assumed or rather guesstimated.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.It also reaches the organisms through respiration along with normal carbon-12.It is assumed that in a living object carbon-14 which undergoes decay is replaced at a steady rate.

Then the amount of carbon-12 in the body will not reduce but the amount of carbon-14 undergoes reduction due its radioactivity.

  1. We have a hard time imagining when these will actually work, but if they do, make sure you check the length of your target’s school transportation. Oh, and we’d love to hear which ones got the biggest laugh for you……so comment below and let us know how your cheesy pick up line delivery went!
