The implication of what is represented by the carbon 14 activity of a sample must be considered. This was a giant leap forward in that it offered far more accurate dates for a far smaller sample 9 ; this made destruction of samples a far less delicate issue to researchers, especially on artefacts such as The Shroud of Turin for which accurate dates were now possible without damaging a significant part of the artefact. The result is the radiocarbon age of the sample. It quickly became apparent that the principles of radiocarbon dating were valid, despite certain discrepancies, the causes of which then remained unknown. By comparing this with a modern standard, an estimate of the calendar age of the artefact can be made. Libby about It is recommended that archaeologists, or any client in general, ask the laboratory if results have systematic or random errors.

Knowing the type of contaminants also give radiocarbon scientists an idea on the pretreatment methods needed to be done before starting carbon dating.

How Does Radiocarbon-14 Dating Work?

Contact our editors with your feedback. Subsequently, a sample from the fossil forest was used in an interlaboratory test, with results provided by over 70 laboratories. This does not mean that we have a precise year of BC, it means we then need to calibrate through other methods that will show us how atmospheric concentrations of the 14 C isotope has changed - most typically through the dendrochronology records tree ring data These counters record bursts of ionization caused by the beta particles emitted by the decaying 14 C atoms; the bursts are proportional to the energy of the particle, so other sources of ionization, such as background radiation, can be identified and ignored. Our sample wheel holds 39 samples. American Chemical Society.
