Carbon dating results

Samples must be stored in packaging materials that will protect them during transport and even during prolonged storage. Labels attached to the packaging materials must not fade or rub off easily. Glass containers can be used when storing radiocarbon dating samples, but they are susceptible to breakage and can be impractical when dealing with large samples. Aluminum containers with screw caps are safe, but it is still best to consult the radiocarbon laboratory for the best containers of carbon dating samples.

It is recommended that archaeologists, or any client in general, ask the laboratory if results have systematic or random errors. They should also ask details about the calibration used for conversion of BP years to calendar years. Clarify the costs involved in radiocarbon dating of samples.

Radiocarbon Dating and Archaeology

Some labs charge more for samples that they do not regularly process. Radiocarbon dating takes time, and laboratories often have waiting lists so this factor must be considered. The carbon dating process is destructive, and labs usually advise their clients with regard to sample identification or labelling. Communication with clients also gives labs an idea of the possible types of contaminants in the excavation site.

Knowing the type of contaminants also give radiocarbon scientists an idea on the pretreatment methods needed to be done before starting carbon dating. Labs ask clients on the expected age of the radiocarbon dating samples submitted to make sure that cross-contamination is avoided during sample processing and that no sample of substantial age more than 10, years must follow modern ones.

Labs also want to avoid processing carbon dating samples that will yield large calendar ranges. Radiocarbon dating results have insignificant value as in the case when the calibration curve is effectively flat and all calendar events in the period will produce about the same radiocarbon age. In either of the cases, it is still worthwhile to carefully consider why the radiocarbon dating results were deemed unacceptable.

Rescue archaeology involves the survey and potential excavation of sites that are to undergo some form of construction or development in order to recover any valuable finds that are uncovered and prevent their destruction. The impending developments leave little time for archaeologists to undertake their work and creates a time-pressured environment with stakeholders eager for them to finish as soon as possible.

In such cases where potentially valuable finds are discovered, fast and high-quality radiocarbon dating results can be crucial in determining whether a site warrants further excavation or can be handed back to the developers. In particular, time-sensitive projects like rescue archaeology , waiting months for test results while construction is halted is not viable and can be a financial burden. Archaeologists need radiocarbon dating laboratories that can cater to their specific project requirements and deadlines.

Accelerator Mass Spectrometry AMS dating involves accelerating ions to extraordinarily high kinetic energies followed by mass analysis. The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited. Beta Analytic does not accept pharmaceutical samples with "tracer Carbon" or any other material containing artificial Carbon to eliminate the risk of cross-contamination.

As good as AMS machines are, simultaneous measurements of the 14C modern standard, sample, and blank cannot be done so small shifts up or down in the detection efficiency of the AMS over the course of the run will affect the accuracy of the result, which at times are outside of the smaller quoted sigma values possible. This is why Beta Analytic only quotes smaller errors by going through the additional effort and cost of running samples multiple times.
