The accuracy of radiocarbon dating

Reference materials are also pressed on metal discs.

Radiometric dating methods detect beta particles from the decay of carbon 14 atoms while accelerator mass spectrometers count the number of carbon 14 atoms present in the sample.

Both carbon dating methods have advantages and disadvantages.

There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry (AMS).

The two techniques are used primarily in determining carbon 14 content of archaeological artifacts and geological samples.

At this stage, molecules that may be present are eliminated because they cannot exist in this triple charged state.

The carbon atoms with triple positive charge further accelerate away from the positive terminal and pass through another set of focusing devices where mass analysis occurs.

Ions from a cesium gun are then fired at the target wheel, producing negatively ionized carbon atoms.

These negatively ionized carbon atoms pass through focusing devices and an injection magnet before reaching the tandem accelerator where they are accelerated to the positive terminal by a voltage difference of two million volts.

QUESTION: Can we improve the accuracy of carbon dating?

ANSWER: Can we improve the accuracy of carbon dating?

After pretreatment, samples for radiocarbon dating are prepared for use in an accelerator mass spectrometer by converting them into a solid graphite form.
