Radiometric dating error margin

Accelerator mass spectrometers need only as little as 20 milligrams and as high as 500 milligrams for certain samples whereas conventional methods need at least 10 grams in samples like wood and charcoal and as much as 100 grams in bones and sediments.

The negatively charged carbon atoms, however, move on to the stripper (a gas or a metal foil) where they lose the electrons and emerge as the triple, positively charged carbon atoms.There are essentially two parts in the process of radiocarbon dating through accelerator mass spectrometry.The first part involves accelerating the ions to extraordinarily high kinetic energies, and the subsequent step involves mass analysis.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.

From these data, concentration ratio of the isotopes can be known to allow evaluation of the level of fractionation.
