Advantages and disadvantages of radiometric dating

An accelerator mass spectrometer has a run time of a few hours per sample.

Lastly, it must be noted that AMS measurements usually achieve higher precision and lower backgrounds than radiometric dating methods.

There are two accelerator systems commonly used for radiocarbon dating through accelerator mass spectrometry.

One is the cyclotron, and the other is a tandem electrostatic accelerator.

At the end of an AMS run, data gathered is not only the number of carbon 14 atoms in the sample but also the quantity of carbon 12 and carbon 13.After pretreatment, samples for radiocarbon dating are prepared for use in an accelerator mass spectrometer by converting them into a solid graphite form.This is done by conversion to carbon dioxide with subsequent graphitization in the presence of a metal catalyst.An accelerator mass spectrometer, although a powerful tool, is also a costly one.Establishing and maintaining an accelerator mass spectrometer costs millions of dollars.
