The following article is primarily based on a discussion of radiocarbon dating found in The Biblical Chronologist Volume 5, Number 1. Full details and references can be found there. Radiocarbon dating is based on a few relatively simple principles. There are many carbon atoms in our environment. The vast majority of these are C (pronounced "c twelve"), the stable isotope of carbon. However, cosmic radiation constantly collides with atoms in the upper atmosphere. Part of the result of these collisions is the production of radiocarbon ( C, pronounced "c fourteen"), carbon atoms which are chemically the same as stable carbon, but have two extra neutrons. Radiocarbon is not stable; over time radiocarbon atoms decay into nitrogen atoms. This tendency to decay, called radioactivity, is what gives radiocarbon the name

Home Events Scholarships Research ... Resources Radiocarbon Dating Dinosaurs? "Carbon dating dinosaur bones is ludicrous, and the fact they yielded numbers is meaningless," says a museum curator. Is it ludicrous or is it the bias of evolutionists that is ludicrous? DIRECT RADIOCARBON DATING OF DINOSAUR BONE FRAGMENTS: The dating of dinosaur fossils is not as simple a matter as the media and mainstream science would like us to believe. There are no magical dating machines generate a report which reads 70 million year old; rather most dating of fossils is done by dating nearby lava flows or other igneous or metamorphic rock assumed to have lost all daughter products and been "set" at the time of the dinosaur or other fossil formation. Then stratagraphic correlation is used to reconstruct the sequence and time. The only method that dates the fossils themselves is carbon dating but evolutionists believe that dinosaurs are too old for carbon dating. This begs the question, are they really that old? In 1970, Professor Robert Whitelaw of Virginia Polytechnic Institute examined the radiocarbon data reported in the journal, Radiocarbon . He was surprised to find that several of these came from specimens which would be considered several million years old by evolutionary dating. Examples are: Sabre-toothed tiger: 28,000 years (evolution: a few million)

Plants take up carbon dioxide gas from the atmosphere and incorporate it into their tissues, and some of that carbon dioxide contains the radioactive isotope carbon-14 (see radiocarbon cycle ). As this decays at a known rate (half of it decays every 5,730 years), the time elapsed since the plant died can be measured in a laboratory. Animals take carbon-14 into their bodies from eating plant tissues and their remains can be similarly dated. After 120,000 years so little carbon-14 is left that no measure is possible (see half-life Radiocarbon dating was first developed in 1949 by the US chemist Willard Libby . The method yields reliable ages back to about 50,000 years, but its results require correction since Libby's assumption that the concentration of carbon-14 in the atmosphere was constant through time has subsequently been proved wrong. Discrepancies were noted between carbon-14 dates for Egyptian tomb artefacts and construction dates recorded in early local texts. Radiocarbon dates from tree rings (see

Much of creationist commentary on the possible errors in 14C is intended to portray the scientific community as being either incompetent or dishonest regarding such issues as the consideration of potential errors in radiometric dating methods. Creationists never discuss the fact that given these analyses, scientists have found ways of identifying and mitigating the effects of these sources of error.

Frustrating uncertainties prevailed until workers understood that their results had to be adjusted for the room's temperature and even the barometric pressure.

Gone are the romantic images of gentlemen in pith helmets carting off treasures to the museums and estates of Europe. Gone, too, is the idea that archaeologists are always on the side of the Bible believer. Modern interpretations frequently challenge biblical accounts. Further, dates generated by new techniques are often at odds with the timing of events given by Scripture. The purpose of this first article is to discuss problems with radiocarbon and tree-ring dating (or dendrochronology), which are the two most common direct dating techniques in archaeology. Problems with relative dating by interpretation of material culture—arrowheads, pottery, tools—will be the subject of the next article.

Shroud of Turin and the Resurrection of Jesus The mended corner of the Shroud of Turin was the cause of the carbon 14 dating failure Carbon 14 dating in 1988 supposedly proved that the Shroud of Turin was medieval. But not everyone was convinced. An overwhelming amount of other data suggested that the Shroud was indeed much older, perhaps first century and from the environs of Jerusalem. Many researchers who were not experts in radiocarbon dating attempted to explain why the carbon 14 dating was wrong. Several ideas were put forward. Some of these explanation gained traction in the media and with the public. One hypothesis was that a serious fire in 1532 that nearly destroyed the Shroud had somehow changed the measurement age of the cloth. Another theory was that a bioplastic-polymer growing on the cloth contaminated the sample. These ideas were scientifically insupportable. Scientists, who were knowledgeable in radiocarbon dating, science dismissed these ideas as preposterous. Photomicrograph of fibers from a warp segment of carbon-14 sample. Chemically, it is unlike the rest of the Shroud.

CARBON-14 DATING MODELS AND EXPERIMENTAL IMPLICATIONS Paul Giem, M.A., M.D. Loma Linda, California Origins WHAT THIS ARTICLE IS ABOUT Eight categories of models for converting carbon-14 dates into real time are discussed. Six of these models are based on a creation as described in Genesis and a short age of life on earth. Differences between the models are specified, especially those that are subject to experimental testing. Such features include (1) differences between ring years and radiocarbon years in trees that should be immediately postdiluvian by creationist theories, (2) the accuracy, or lack thereof, of the dendrochronological radiocarbon calibration curve in the historical era, and (3) the possible existence of carbon-14 in antediluvian fossil material. Suggestions are offered for experimental projects that would resolve these uncertainties. In this paper I will discuss eight categories of carbon-14 models and their experimental implications. Six, or three-quarters of these, are creationist models. The purpose of this paper is to stimulate thinking and to argue for an experimental perspective. CONSTRAINTS Any model of carbon-14 dating must satisfy certain constraints. First, since carbon-14 dating is objective and reproducible, it cannot be ignored. One cannot simply dismiss it out of hand; there should be an explanatory model for the data. Second, it has been validated at least back to 300 B.C. by comparison with many other reliable dating methods.

32. Radiocarbon Dating This article follows Mary Hudson s excellent description of the basis of radiocarbon dating in the April 1997 edition of the Aucilla River Times. http://www.flmnh.ufl.edu/natsci/vertpaleo/aucilla12_1/radio99.htm

More about radiocarbon dating By David Thulman The great promise of radiocarbon (C14) dating is that it provides a method for dating and sequencing specific prehistoric events. On the Aucilla projects, C14 dating is used as a method for weeding out unpromising sties that are either too old or too young. In addition, it provides a method for determining the relative chronologies at the various sites and their relation to sites elsewhere in the world. Are we working on some of the earliest human cultural remains in North America? C14 dating can help provide the answer. Given the pervasive reliance on C14 dating in archeology, it is necessary to understand the limitations of C14 dating and how the results can be skewed and misused. A C14 date is not really a “date” at all; it is an estimation of the number of years it would take the radioactive carbon in a dead organism to decay to leave the amount of radioactive carbon actually found when a sample of that organism is analyzed. Carbon 14 dating is based upon a number of important assumptions, but only one will be discussed here. In order to compare C14 dates meaningfully, we must assume that all organisms contained the same amount of C14 when they died. Otherwise, organisms with less C14 will appear older because there will be less C14 than expected when the sample is tested. Unfortunately, that assumption is faulty. As Mary Hudson explained in her Aucilla River Times article two years ago, C14 is created by cosmic radiation in the upper atmosphere. That radiation fluctuates year to year and therefore so does the creation of C14 . That means if our branch grew at a time when relatively lower levels of C14 were in the atmosphere, it would have less C14 when it died and would show an older apparent age than it should. Conversely, if it grew at a time of abundant C14 it would appear younger than it should. This differential C14 concentration may give our branch a younger C14 age than another branch that died hundreds of years after our branch, making comparison of the two samples misleading.

It may well go down as the biggest radiocarbon dating mistake in history; not because there is anything wrong with the measurement process (there may not have been); not because there is anything inherently wrong with carbon 14 dating (there is not); not because of shoddy sample taking (which indeed was shoddy); not because of red flags that should have raised serious questions (there were quite a few); and not even because a basic tenet of archaeological dating was ignored by good scientists. No, the reason is because, now, nearly two decades later, whenever carbon 14 dating is discussed in high school or college classrooms, students are likely to raise a hand and ask some probing questions: What about the Shroud of Turin? Was it dated correctly? If not, how could so many scientists from so many reputable radiocarbon dating laboratories screw up so badly? Were mistakes made in the radiocarbon dating of the shroud? Were enough serious mistakes made to call the results into question?

Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates to active substances such as hormones. All carbon atoms have a nucleus containing six protons. Ninety-nine percent of these also contain six neutrons. The 6 proton + 6 neutron atoms are said to have a mass of 12 and are referred to as "carbon-12." The nuclei of the remaining one percent of carbon atoms contain not six but either seven or eight neutrons in addition to the standard six protons. They have masses of 13 and 14 respectively and are referred to as "carbon-13" and "carbon-14."

35. The Pitfalls Of Radiocarbon Dating Speaking of my research as far as it affects the radiocarbon dating method, I would like to separate the finds concerning natural events (Worlds in http://www.varchive.org/ce/c14.htm

The Pitfalls of Radiocarbon Dating Offering in 1952 his new radiocarbon method for calculating the age of organic material (the time interval since the plant or the animal died), W. F. Libby clearly saw the limitations of the method and the conditions under which his theoretical figures would be valid: A. Of the three reservoirs of radiocarbon on earth—the atmosphere, the biosphere, and the hydrosphere, the richest is the last—the oceans with the seas. The correctness of the method depends greatly on the condition that in the last 40 or 50 thousand years the quantity of water in the hydrosphere (and carbon diluted in it) has not substantially changed. : B. The method depends also on the condition that during the same period of time the influx of cosmic rays or energy particles coming from the stars and the sun has not suffered substantial variations. To check on the method before applying it on various historical and paleontological material, Libby chose material of Egyptian archaeology, under the assumption that no other historical material from over 2,000 years ago is so secure as to its absolute dating. When objects of the Old Kingdom and Middle Kingdom of Egypt yielded carbon dates that appeared roughly comparable with the historical dates, Libby made his method known. But as the method was refined, it started to show rather regular anomalies. First, it was noticed that, when radiocarbon dated, wood grown in the 20th century appears more ancient than wood grown in the 19th century. Suess explained the phenomenon by the fact that the increased industrial use of fossil carbon in coal and in oil changed the ratio between the dead carbon C12 and the C14 (radiocarbon) in the atmosphere and therefore also in the biosphere. In centuries to come a body of a man or animal who lived and died in the 20th century would appear paradoxically of greater age since death than the body of a man or animal of the 19th century, and if the process of industrial use of fossil, therefore dead, carbon continues to increase, as it is expected will be the case, the paradox will continue into the forthcoming centuries.

Willis Harry Godwin Bill Libby Alfred Maddock Nick Shackleton Richard West Hessel de Vries The first counter The first dates Bomb radiocarbon Stratospheric radiocarbon sampling Generally speaking, it was the sounder and more confident heads in the community who sought grants to start the early Radiocarbon Laboratories. It was customary to then prevail on some well known physics or chemistry professor to supply the technical expertise, and he in turn would select some unsuspecting graduate student to build it. Graduate students were among the few at that time who could even spell the magic words 'nucleonics', 'electronics' and 'vacuum lines' born of hush-hush wartime technologies. In many ways the era was analogous to today's computer explosion where fortune favours the young and the brave. One may detect the deliberate use of the word 'build', and not 'operate' for, as we shall see, few had discovered the magic formula for making it work. It was in this firmament of hope compounded by confusion that rewarding careers began and lifelong friendships were forged. It was thus in early 1952 that Harry Godwin, who had recently formed the University Sub-Department of Quaternary Research in the Botany School, applied for a grant from the Nuffield Foundation of eight thousand pounds over five years to create the Cambridge Laboratory. Harry secured the enthusiastic advice of Alfred Maddock, a radiochemist by avocation and a walking encyclopaedia by nature, to steer the technical side. I had met Alfred at a Radiation Chemistry Conference in Leeds in April of 1952, and was as impressed with his capacity then as I am forty-four years later. Alfred had spent the War working on secret atomic matters in Canada, and his moment of glory had come when he recovered the entire stock of Canada's plutonium from the sawn-up pieces of a laboratory bench top - how it got there in the first place is a matter which the faithful never discuss.

The 1984 radiocarbon dates from monuments spanning Dynasty 3 (Djoser) to late Dynasty 5 (Unas), averaged 374 years older than the Cambridge Ancient History The 1995 Project. Old Kingdom Problem. If the Middle Kingdom radiocarbon dates are okay, why are the Old Kingdom ones from pyramids so problematic? The pyramid builders used older cultural material, whether out of expedience or to make a conscious connection between their pharaoh and his predecessors. In galleries under the pyramid of the Dynasty 3 pharaoh Djoser more than 40,000 stone vessels were found. Inscriptions on them included most of the kings of Dynasty 1 and 2, but Djoser's name occurred only once. Perhaps Djoser gathered up the vases from the 200-year-old Archaic tombs at North Saqqara. In Dynasty 12, Amenemhet I actually took bits and pieces of Old Kingdom tomb chapels and pyramid temples (including those of the Giza Pyramids) and dumped them into the core of his pyramid at Lisht. At Giza, south of the Sphinx, we are excavating remains of facilities for storage and production of fish, meat, bread, and copper that date to the middle and end of Dynasty 4, when the pyramids of Khafre and Menkaure were under construction. Three of the eight dates from samples taken here are almost direct hits on Menkaure's historical dates, 2532- 2504 B.C. The other five, however, range from 350 to 100 years older. Our radiocarbon dates from the site suggest that, like those from the pyramids, the dates on charcoal from the settlement scatter widely in time with many dates older than the historical estimate. The pyramid builders were likely recycling their own settlement debris.

Explain how carbon can help determine the age of a fossil. As you learned in the previous page, carbon dating uses the half-life of Carbon-14 to find the approximate age of an object that is 40,000 years old or younger. In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works. What exactly is radiocarbon dating? Radiocarbon dating is a method of estimating the age of organic material. It was developed right after World War II by Willard F. Libby and coworkers, and it has provided a way to determine the ages of different materials in archeology, geology, geophysics, and other branches of science. Some examples of the types of material that radiocarbon can determine the ages of are wood, charcoal, marine and freshwater shell, bone and antler, and peat and organic-bearing sediments. Age determinations can also be obtained from carbonate deposits such as calcite, dissolved carbon dioxide, and carbonates in ocean, lake, and groundwater sources.

40. RADIOCARBON DATING AND SCRIPTURE This essay briefly describes the accuracy of the book of Genesis based on radiocarbon (C14) and archaeological evidence. http://www.geocities.com/peaceharris/c14/

Abstract This essay attempts to show the reader that the first book of Moses, commonly called Genesis, is accurate. To prove its accuracy, archaeological evidence based on radiocarbon dating is used. We first model the variation of radiocarbon in the atmosphere assuming that scripture is accurate, then verify whether or not observed data fits this model. Introduction to C14 dating C is produced in the atmosphere when neutrons from cosmic rays bombard nitrogen. N + n - > C + p (i) C is oxidized instantly to C O . C being unstable, decays back to N with a half-life of 5700 years, releasing an electron. C - > N + e (ii) It is commonly assumed that the rate of C production is equal to the rate of decay, hence the percentage of C in the atmosphere remains constant. C and C are stable isotopes. The relative abundance of these isotopes in atmospheric CO is as follows: C C C As long as an animal / human is alive, the percentage of C present in his body is the same as that in the atmosphere. This is because the food that we eat ultimately comes from plants. And carbon present in plants is produced from atmospheric CO during photosynthesis.
