method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of radiocarbon dating limitations cosmic rays with atmospheric nitrogen. The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire 14C by eating the plants.
Carbon Dating Explained
When the animal or plant dies, it stops exchanging carbon with its environment, and from that point onwards the amount of 14C it contains begins to decrease as the 14C undergoes radioactive decay. Measuring the amount of 14C in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to carbon dating math problems calculate when the animal or plant died. The older a sample is, the less 14C there is to be detected, and because the half-life of 14C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by radiocarbon dating are around 50,000 years ago, although special preparation methods occasionally permit dating of older samples. The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained. Research has been ongoing since the 1960s to determine what the proportion of 14C in the atmosphere has been over the past fifty thousand years. The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age. Other corrections must be made to account for the proportion of 14C in different types of organisms (fractionation), and the varying levels of 14C throughout the biosphere (reservoir effects).

Aardsma, Ph.D. Resources › Physical Sciences Resources › Radiometric Dating The field of radiocarbon dating has become a technical one far removed from the naive simplicity which characterized its initial introduction by Libby in the late 1940's. It is, therefore, not surprising that many misconceptions abo
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. http://www.flmnh.ufl.edu/vertpaleo/aucilla12_1/radio99.htm Are we working on some of the earliest human cultural remains in North America? http://rationalwiki.org/wiki/Carbon_dating 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 dating carbon in a dead organism to decay to leave the amount of radioactive carbon actually found when a sample of that organism is analyzed. For example, at the Aucilla River sites, we typically take samples of buried tree branches for C14 testing. (Wood is a very reliable material for C14 testing.) The ratio of C14 and C12 in that branch is then compared with the ratio of C14 and C12 in a modern standard, radiocarbon dating error and an estimate is made of the C14 remaining in the branch. If half the amount of C14 in the modern standard is left in the branch, the branch should be about 5,730 years old. I say “about” since the decay of C14 is random and the estimation of the amount of C14 is based in part on statistics. That is why C14 dates are always reported with a “±” margin of error. Typically, the margin of error reported is for one standard deviation from the norm. Therefore, a C14 date of 10,000 ± 200 BP on our branch sample means there is a 68% probability (a 2 in 3 chance) the branch died sometime between 9,800 and 10,200 years ago. A common practice is to report a C14 date as the single middle date (in our example, 10,000 years). This is misleading since there is actually an equal chance the true date of the branch will fall anywhere within the 400 year margin of error. 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 C1

It depends upon the radioactive decay of carbon-14 (14C), an unstable isotope of carbon which is continually synthesized in the upper atmosphere by cosmic rays. Plants take up atmospheric 14C for as long as they live, through the process of photosynthesis. Animals take up atmospheric 14C indirectly, by eating plants (or eating other animals that eat plants). Measuring the proportion of 14C as opposed to 12C remaining in a sample then tells us how long ago the sample stopped taking up 14C -- in other words, how long ago the thing died. Carbon dating has a certain margin of error, usually depending on the age and material of the sample used. Carbon-14 has a half-life of about 5730 years, and therefore it is used to date biological samples up to about 60,000 years in the past. Beyond that timespan, the amount of the original 14C remaining is so small that it cannot be reliably distinguished from 14C formed by irradiation of nitrogen by neutrons from the spontaneous fission of uranium, present in trace quantities almost everywhere. For these samples, other dating methods must be used. The level of atmospheric 14C is not constant due to human activity, in part because of human combustion of fossil fuels and in part because of above-ground testing of the largely defensive weapon of the thermonuclear bomb. Therefore dates must be calibrated based on 14C levels in samples of known ages.[1] Heather Graven, an a
