Radiometric dating of sediments

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

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.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.Due to the sensitivity of accelerator mass spectrometers, carbon dating small particles like blood particles, a grain, or a seed have been made possible.
