Carbon dating is accurate

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.

At this stage, other negatively charged atoms are unstable and cannot reach the detector.

These metal discs are then mounted on a target wheel so they can be analyzed in sequence.

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

A method has finally been developed to detect carbon 14 in a given sample and ignore the more abundant isotopes that swamp the carbon 14 signal.

There are essentially two parts in the process of radiocarbon dating through accelerator mass spectrometry.

Both carbon dating methods have advantages and disadvantages.

Mass spectrometers detect atoms of specific elements according to their atomic weights.

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

These two radiocarbon dating methods use modern standards such as oxalic acid and other reference materials.

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

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

Although both radiocarbon dating methods produce high-quality results, they are fundamentally different in principle.
