Carbon-14 dating cannot be applied to materials that have no C dates are less than that figure.

This can be done very accurately, although some samples may be difficult to work with.

Beyond this, the accuracy of the date depends on the reliability of the assumptions used in interpreting the measurements (see below).

Other processes may affect the local concentrations of carbon-14.

These effects are corrected for by comparing samples from different locations.

While the small variations in isotope decay that have been reported may not invalidate all isotopic dating, they raise questions about the assumption of completely uniform decay rates.

A second assumption is that the sample being dated has not experienced any loss or contamination of C over its history.
