Uncertainty with carbon 14 dating Free online adult private text chat
One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains.
This is a radiometric technique since it is based on radioactive decay.
Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy.
Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events.
For example, modern biblical chronology dates Noah's Flood to 3520 /- 21 B.
Absolute dating is the process of determining an age on a specified chronology in archaeology and geology.
Radiocarbon dates are certainly not precise to within a year or two, but they are generally precise to within a few hundred years or better.
This means radiocarbon's precision is generally sufficient to choose between alternate chronologies which differ by a hundred years or more.
Thus there are statistical counting uncertainties proportional to the square root of the number of atoms counted.Modern accelerator mass spectrometry (used for radiocarbon dating purposes to separate radiocarbon atoms from stable carbon atoms and count them) is quite precise.The technology involved is fascinating and impressive.A common misconception about radiocarbon dating is that it gives a precise date---3577 B. In actual practice radiocarbon dating can only give a range of dates for a given sample---3650 to 3410 B.C., for example---the true date lying somewhere in that range.
