Chronological Methods 8 - Radiocarbon Dating Radiocarbon, or Carbon-14, dating is probably one of the most widely used and best known absolute dating methods. It was developed by J. R. Arnold and W. F. Libby in 1949, and has become an indispensable part of the archaeologist's tool kit since. It's development revolutionized archaeology by providing a means of dating deposits independent of artifacts and local stratigraphic sequences. This allowed for the establishment of world-wide chronologies.
Where does C -14 Come From? Radiocarbon dating relies on a simple natural phenomenon. As the Earth's upper atmosphere is bombarded by cosmic radiation, atmospheric nitrogen is broken down into an unstable isotope of carbon - carbon 14 (C-14). Bombardment Reactions The unstable isotope is brought to Earth by atmospheric activity, such as storms, and becomes fixed in the biosphere. Because it reacts identically to C-12 and C-13, C-14 becomes attached to complex organic molecules through photosynthesis in plants and becomes part of their molecular makeup. Animals eating those plants in turn absorb Carbon-14 as well as the stable isotopes. This process of ingesting C-14 continues as long as the plant or animal remains alive. Diffusion Ingestion
C-14 Decay Profile The C-14 within an organism is continually decaying into stable carbon isotopes, but since the organism is absorbing more C-14 during its life, the ratio of C-14 to C-12 remains about the same as the ratio in the atmosphere. When the organism dies, the ratio of C-14 within its carcass begins to gradually decrease. The rate of decrease is 1/2 the quantity at death every 5,730 years. That is the half-life of C-14. The animation provides an example of how this logarithmic decay occurs. Click on the "Show Movie" button below to view this animation.

Carbon Dating
Carbon dating is a variety of radioactive dating which is applicable only to matter which was once living and presumed to be in equilibrium with the atmosphere, taking in carbon dioxide from the air for photosynthesis. Cosmic ray protons blast nuclei in the upper atmosphere, producing neutrons which in turn bombard nitrogen, the major constituent of the atmosphere . This neutron bombardment produces the radioactive isotope carbon-14. The radioactive carbon-14 combines with oxygen to form carbon dioxide and is incorporated into the cycle of living things. The carbon-14 forms at a rate which appears to be constant, so that by measuring the radioactive emissions from once-living matter and comparing its activity with the equilibrium level of living things, a measurement of the time elapsed can be made.

Presuming the rate of production of carbon-14 to be constant, the activity of a sample can be directly compared to the equilibrium activity of living matter and the age calculated. Various tests of reliability have confirmed the value of carbon data, and many

Since there's very little C, we'll ignore it in this discussion of dating. from the atmosphere, absorb sunlight, and undergo photosynthesis the carbon is used as food to cause the plant to grow, while the oxygen is released back into the atmosphere. as waste. In this way, both plants and animals are constantly exchanging carbon and oxygen with that in the atmosphere. While they are alive, their bodies contain the same fraction of the three carbon isotopes as does the atmosphere, but at death, respiration ceases and the exchange stops. Since C constantly decays (with a 5,730-year half-life), the fraction of C in a dead body is always diminishing. After 5,730 years, the fraction of

C and Snails
You have probably heard of Carbon-14 , also written C . C is a radioactive form of carbon produced in the outer atmosphere when cosmic rays transform atoms of regular nitrogen . Being radioactive and thus unstable, C "decays" at a certain predictable rate. Its decay rate is such that half of any given quantity of it will convert back to nitrogen in about 5,730 years. Then half of the remainder will be gone in the next 5,568 years, etc. The fancy way of saying this is that C 's half life is 5,568 years. There's a good site on the Web for finding more detailed information on C dating. C 's remarkable behavior is very useful to us because of two further fabulous facts: First, despite its strange manner of having a half life, it behaves just like regular carbon as it cycles through the ecosystem, sometimes as a constituent of the gas carbon dioxide, or CO , sometimes as a carbohydrate inside a plant's body, or whatever. The second fabulous fact about C is that since it both appears and disappears at given rates, and surely has been doing so ever since Earth had an atmosphere with nitrogen in it, it can be assumed that the ratio between regular carbon and C

Creation Science Prophecy: Carbon 14 Dating
A creationist source that makes an argument about anomalous C in coal deposits.
The Problem: Accelerator mass spectrometry (AMS), a sensitive radiometric dating technique, is in some cases finding trace amounts of radioactive carbon-14 in coal deposits, amounts that seem to indicate an age of around 40,000 years. Though this result is still too old to fit into any young-earth creationist chronology, it would also seem to represent a problem for the established geologic timescale, as conventional thought holds that coal deposits were largely if not entirely formed during the Carboniferous period approximately 300 million years ago. Since the halflife of carbon-14 is 5,730 years, any that was present in the coal at the time of formation should have long since decayed to stable daughter products. The presence of C in coal therefore is an anomaly that requires explanation. The Solution: Talk.origins' Kathleen Hunt wrote an e-mail to a noted expert on AMS and

http://www.users.globalnet.co.uk/~freya01/carbon14.htm
Radiocarbon Dating Cosmic radiation constantly bombards atoms in the upper atmosphere and splits them up into their components. Nitrogen atoms colliding with neutrons formed in this way can undergo a radioactive transformation into carbon-14: The atoms of carbon-14 formed formed in this process are converted into radioactive molecules of carbon dioxide, which dissipate throughout the atmosphere. As with normal carbon-12 carbon dioxide, these molecules are absorbed by plants, and as a result the carbon-14 is incorporated into them. The plants are eaten by animals and so all living things, plants or animals, will contain a small amount of radioactive carbon-14. Carbon-14 slowly decays to nitrogen in a second radioactive process:: There is a constant level of carbon-14 present in all living things, which is brought about by the equilibrium established between the absorption of the carbon-14 and its natural decay. This value is very low, but is detectable either from radioactivity measurements or from mass spectrometry. When a plant or an animal dies, it stops absorbing carbon-14 and so the amount present slowly decreases due to radioactive decay. The half life of carbon-14 is approximately 5 600 years, and so the level of radioactivity drops to half its original value in this time. The degree to which this radioactivity has fallen is used to estimate the age (or at least the time since death) of the animal or plant. The famous Turin shroud was found to be a medieval artefact from radiocarbon dating

The Short Summary
Carbon dating can be used on material which was living in the last few tens of thousands of years, and which got its carbon from the air. The method has become more accurate in the last few decades.
The Theory
Carbon 14 is a radioactive isotope of carbon. It is produced in the upper atmosphere by radiation from the sun. (Specifically, neutrons hit nitrogen-14 atoms and transmute them to carbon.) Land plants, such as trees, get their carbon from carbon dioxide in the air. So, some fraction of their carbon is C14. The same is true of any creature that gets its carbon by eating such plants. We can measure this in living things today. Suppose such a creature dies, and the body is preserved. The C14 will undergo radioactive decay, and after 5730 years, half of it will be gone. Eventually, all of it will be gone. So, if we find such a body, the amount of C14 in it will tell us how long ago it was alive.

BY: THOMAS HIGHAM "Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure. We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 1989:71)]. Nyerup's words illustrate poignantly the critical power and importance of dating; to order time. Radiocarbon dating has been one of the most significant discoveries in 20th century science. Renfrew (1973) called it 'the radiocarbon revolution' in describing its impact upon the human sciences. Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species. Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7). Writing of the European Upper Palaeolithic, Movius (1960) concluded that

http://www.anthro.mankato.msus.edu/archaeology/dating/radio_carbon.html
Index Radio-carbon dating is a method of obtaining age estimates on organic materials. It has been used to date samples as old as 50,000 years. The method was developed immediately following World War II by Willard F. Libby and coworkers, and has provided age determinations in archaeology, geology, geophysics and other branches of science. Radiocarbon determinations can be obtained on wood; charcoal; marine and fresh-water shell; bone and antler; peat and organic-bearing sediments, carbonate deposits such as tufa, caliche, and marl; and dissolved carbon dioxide and carbonates in ocean, lake and ground-water sources. Each sample type has specific problems associated with its use for dating purposes, including contamination and special environmental effects. While the impact of radiocarbon dating has been most profound in archaeological research and particularly in prehistoric studies, extremely significant contributions have also been made in hydrology and oceanography. In addition, in the 1950s the testing of thermonuclear weapons injected large amounts of artificial radiocarbon ("Radiocarbon Bomb") into the atmosphere, permitting it to be used as a geochemical tracer. To discover how long an organism has been dead (to determine how much C14 is left in the organism and therefore how old it is), we count the number of beta radiations given off per minute per gram of material. Modern C14 emits about 15 beta radiations per minute per gram of material, but C14 that is 5730 years old will only emit half that amount, (the half-life of C14) per minute. So if a sample taken from an organism emits 7.5 radiations per minute in a gram of material, then the organism must be 5730 years old. The accuracy of radiocoarbon dating was tested on objects with dates that were already known through historical records such as parts of the dead sea scrolls and some wood from an Egyptian tomb. Based on the results of the Carbon 14 test the analysis showed that C14 agreed very closely with the historical information.

Introduction:
A speculative research paper examining current evidence available on Neanderthal man with comparison to references in early manuscripts of the Nephilim an ancient race of half-breed humans. The argument is presented that the scientific facts verify that the Neanderthal were in fact one and the same as the ancient warrior race the Nephilim. It is here proposed that an examination of the evidence and facts currently available on Neanderthal man reveal that they could well have been a race of half-breed humans referred to in some of the earliest manuscripts found as the Nephilim.
Background:
Neanderthal man has become an enigma to science once being hailed as the proof of the evolution of apes to modern man. He was considered to be the brutish ancestor link to man in the evolution chain, the intermediate stage between man and ape.
Now! Neanderthal is recognised by scientists as a contemporary of modern man living alongside humans having many human attributes. But amazingly with a LARGER brain than mans! Were they the Nephilim?
