We are always seeking to keep turn-around times to a minimum but some delay is inevitable because of the complexity of the dating process and because of fluctuations in demand.The current estimated turnaround time for commercial samples submitted now is: Samples should be well protected in packaging that is not likely to contaminate the samples.Nothing on earth carbon dates in the millions of years, because the scope of carbon dating only extends a few thousand years.Willard Libby invented the carbon dating technique in the early 1950's.Water samples should be stored in inert plastic bottles with tightly sealed screw tops and a negligible air gap.Samples are normally taken within the laboratory where we have all the necessary facilities.Please see section on sample section and identification to determine the types of material suitable for analysis and for information on restrictions on what we can date.Also see our information on methods for further information including the expected precision of our measurements.
Just this one fact totally upsets data obtained by C-14 dating.
For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms.
Radiocarbon dating is one such type of radiometric dating.
A freshly created earth would require about 30,000 years for the amount of C-14 in the atmosphere to reach this point of equilibrium because it would leak out as it is being filled.
Tests indicate that the earth has still not reached equilibrium.
