Buckland's immediate successors did a little better.
The C-14 decays with the beta particle, and you have some detection equipment and you count the C-14s one by one.
Accelerator mass spectrometry is not dependent upon the radioactive decay.
What you’re doing is measuring all of the carbon isotopes in the sample – the 12, 13 and 14 – the accelerator operates like a giant mass spectrometer.
A mass spectrometer is an instrument that uses a series of magnets to bend a beam of ions and then physically count how many there are, so with AMS radiocarbon dating, we can measure a carbon-12, 13 and 14 beam, and we measure the ratio of 14 to 13, and from that, we can tell how much C-14 is in the sample.
