AMS research journals fall under two models of open access, green and gold:. The AMS considers any version of the paper up to the final peer-reviewed manuscript including revisions that take into account comments and suggestions of referees to be a prepublication version. In this model, there are no processing fees and the article is included in a subscription journal. All AMS subscription research journals are green open access journals. With gold open access, the AMS makes the final published version of an article freely available electronically immediately upon publication. APCs are not expected to be paid by the author personally. Resources for finding Open Access funding can be found here. In order to ensure the high editorial standard of each new journal, Proceedings of the AMS, Series B , and Transactions of the AMS, Series B, share common editorial boards, and thus submission procedures, with their companion journals. In addition, editorial decisions are completely independent of whether a paper is intended for the open access journal or its subscription counterpart.

The application of radiocarbon dating to determine the geochronology of archaeological sites is ubiquitous across the African continent. However, the method is not without limitations and this review article provides Africanist archaeologists with cautionary insights as to when, where, and how to utilize radiocarbon dates. Specifically, the review will concentrate on the potential of carbon reservoirs and recycled organic remains to inflate apparent age estimates, diagenesis of carbon isotopes in variable pH ecologies, and hot-humid climates and non-climate-controlled archives that can compromise the efficacy of samples.

Radiocarbon dating: radioactive carbon decays to nitrogen with a half-life of years. In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly. To obtain a truly absolute chronology, corrections must be made, provided by measurements on samples of know age. The most suitable types of sample for radiocarbon dating are charcoal and well-preserved wood, although leather, cloth, paper, peat, shell and bone can also be used.

Because of the somewhat short half-life of 14C, radiocarbon dating is not applicable to samples with ages greater than about 50, years, because the remaining concentration would be too small for accurate measurement.

An extra charge may be made for samples requiring special or difficult processing methods, following consultation with the submitter. Prices may be reviewed at.

The Radiocarbon Dating Laboratory in Lund performs dating on geological and archaeological samples. Examples of material that we date are wood, charcoal, peat, macrofossils, bone and marine shells. We also measure 14C in modern samples for determination of biomass content in e. Radiocarbon dating is based on the radioactive decay of 14C in dead tissues, which can be used to calculate the time that has elapsed since death occurred.

This is possible since organisms have the same 14C content as the environment in which they live. After the death of the organism, the carbon which survives decomposition continuously loses 14C in relation to its content of stable 12C. Our lab performs high-quality analyses and is committed to continual quality control to ensure that the precision and accuracy of our 14C measurements dates are maintained at the highest level.

We routinely include secondary standards of different ages and sizes in our measurements. Radiocarbon to test and ensure the quality of our analyses. Research at our lab has contributed to the improvement of the recently published IntCal20 calibration curve crucial to transfer 14C ages into calendar ages Adolphi et al.

One of the aims was to minimize measurement cost by emphasizing large scale projects plus encouraging users to carry out sample processing at their own institutions. Researchers from other fields or submitters with fewer than ten samples are encouraged to contact other AMS facilities or commercial dating services: small batches or samples from other fields will be run by special arrangement only. Contact information for other laboratories can be found at the Radiocarbon journal web site, at www.

Submitters, and in particular those making their first application, must make contact with the laboratory to discuss their requirements prior to actually submitting samples. See contacts for more info. A submission form plus a sample list provided must be filled out see guidance document for each group of samples submitted and sent to us via mail, fax or e-mail.

We understand that in radiocarbon dating, each sample is unique. For this ICA does not apply a fee if a date cannot be generated. PRICES. Valid until December 31, ICA will not charge you if we can not get a date from your sample.

Accelerator mass spectrometry AMS is a form of mass spectrometry that accelerates ions to extraordinarily high kinetic energies before mass analysis. The special strength of AMS among the mass spectrometric methods is its power to separate a rare isotope from an abundant neighboring mass “abundance sensitivity”, e. This makes possible the detection of naturally occurring, long-lived radio-isotopes such as 10 Be, 36 Cl, 26 Al and 14 C.

AMS can outperform the competing technique of decay counting for all isotopes where the half-life is long enough. Generally, negative ions are created atoms are ionized in an ion source. In fortunate cases, this already allows the suppression of an unwanted isobar, which does not form negative ions as 14 N in the case of 14 C measurements. The pre-accelerated ions are usually separated by a first mass spectrometer of sector-field type and enter an electrostatic “tandem accelerator”.
