Routine Quality Assurance in the Suerc Radiocarbon Laboratory
The SUERC Radiocarbon Laboratory reports approximately 3000 unknown samples per year with an additional 1200 samples processed for quality assurance purposes. In addition to the primary OxII standard (SRM-4990C) required for AMS batch normalization, secondary “known-age” standards have been used over many years to evaluate individual batch quality. These have included wood (as prepared alpha-cellulose), barley mash, humic acid, a background mammo…
Carbon Isotope Changes Through the Recent Past
Radiocarbon (F 14 C) and stable carbon (δ 13 C) values were measured in single grains of spring barley (Hordeum vulgare L. ) from the sample archive from two adjacent sites of the Long-term Experiments (LTEs) Hoosfield Spring Barley at Rothamsted Research (Harpenden, Hertfordshire, UK), covering the growing periods (March to September) of 1852 to 2020. F 14 C data of the barley grain confirm that recent values are approaching and will decline bel…
Preliminary Results for Estimating the Bone Background Uncertainties at Suerc Using Statistical Analysis
Bone is frequently dated in archaeological studies and, especially for very old bones (more than 40,000 years old), it is critical to have an accurate and precise measure of the material-specific background value and its associated uncertainty. The SUERC Radiocarbon Laboratory has obtained a mammoth bone as a background bone standard and an appropriate number are now routinely prepared and measured in each AMS batch, resulting in the accumulation…
Investigation of the Analytical F 14 C Bone Background Value at Suerc
The SUERC Radiocarbon Laboratory employs a one-step “background subtraction” method when calculating 14 C ages. An interglacial wood (VIRI Sample K) is employed as the non-bone organic background standard, while a mammoth bone (LQH12) from Latton Quarry is used as the bone background standard. Results over several years demonstrate that the bone background is consistently around a factor of two higher and more variable than the wood background. A…
AMS 14 C Dating at the Scottish Universities Environmental Research Centre (Suerc) Radiocarbon Dating Laboratory
This paper describes all the major procedures adopted by the Scottish Universities Environmental Research Centre (SUERC) Radiocarbon Dating Laboratory. This includes sample pretreatment, graphite production, accelerator mass spectrometry (AMS) measurement, associated stable isotope measurements, data handling, and age calculations, but with the main emphasis being on the chemical pretreatment methods. All of the above enable the laboratory to pro…
