Fluoride ions are present in trace amounts in most soils and groundwaters.

The half life of carbon-14 is about 5,700 years, so if we measure the proportion of C-14 in a sample and discover it's half a part per trillion, i.e.

Accelerator mass spectrometry measures the amount of carbon-14, or radiocarbon, present in a sample, which can be used to calculate its age.

With our current kit 40-50K years is about the limit.
