There are several other possible sources of error that need to be considered. Measurement of Nthe number of 14 C atoms currently in the sample, allows the calculation of tthe age of the sample, using the equation above. New Fluorescence Spectrometers Accurately Analyse a A 14 C signal from the process blank measures the amount of contamination introduced during the preparation of the sample. The half-life of carbon is 5, years, which means that it will take this amount of time for it to reduce from g of carbon to 50g — exactly half its original amount.

What happened, from what I recall, is that someone hacked TalkOrigins and managed to get the site to display hidden spam links at the bottom of pages, making Google think it was a spam site and thus getting it removed from Google.
It should be no surprise then, that fully half of the dates are rejected.
Thanks to Fossil Fuels, Carbon Dating Is in Jeopardy. One Scientist May Have an Easy Fix
Lunisolar Solar Lunar Astronomical year numbering. Posted December 29, edited. Errors in procedure can also lead to errors in the results. Calibrated dates should also identify any programs, such as OxCal, used to perform the calibration. With the development of AMS in the s it became possible to measure these isotopes precisely enough for them to be the basis of useful dating techniques, which have been primarily applied to dating rocks.
