A level physics carbon dating

The unstable Carbon-14 is transported down to the lower atmosphere by atmospheric activity such as storms.

Carbon-14 reacts identically to Carbon-12 and is rapidly oxidised to form (Carbon-14)Dioxide.

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

Radiocarbon or Carbon-14 dating is a technique used by scientist to date bones, wood, paper and cloth. It is produced in the Earth’s upper atmosphere when Nitrogen-14 is broken down to form the unstable Carbon-14 by the action of cosmic rays.

This isotope Carbon-14 has a half life of 5,700 years.The trouble is that after 40,000 years there is under 1% of the original C-14 left, and it becomes too hard to measure it accurately.This isn't a fundamental limit as more accurate measurements could go further back, but at some point you'd simply run out of C-14 atoms.half the original level, we know the sample is around one half life or 5,700 years old.So by measuring the C-14 level we work out how many half lives old the sample is and therefore how old it is.
