Conventional radiocarbon dating

The laboratory currently has the capacity to produce around 5000 AMS targets per annum, of which approximately 3500 would be unknown age samples and 1500 would be standards.

In contrast, however, the oceans and the life that they support represent a rather heterogeneous reservoir that is not in equilibrium with the atmosphere.

The four fundamental assumptions in the conventional radiocarbon dating method are that: C uptake ceases and only radioactive decay (which follows first order kinetics) then occurs.

The SUERC laboratory undertakes collaborative research within the university sector as well as its own in-house research and has received research funding from a variety of bodies including the UK Research Councils, the Leverhulme Trust, the UK Nuclear Industry, the Commission of European Communities, International Atomic Energy Agency, Historic Scotland and English Heritage.

The commercial wing of the laboratory undertakes radiocarbon analyses in a number of fields but the main focus is archaeology.

For clarity, both radiocarbon laboratories are managed by SUERC.

The NERC Radiocarbon Facility (Environment) was established to meet the need within the UK for radiocarbon analyses in NERC-supported areas of environmental and Earth sciences.The former satisfies the requirements of the Glasgow University, Edinburgh University and NERC cosmogenic isotope preparation facilities as well as the SUERC Radiocarbon Dating Laboratory and the Natural Environment Research Council (NERC) Radiocarbon Facility (Environment).The SSAMS is dedicated to making measurements for the two radiocarbon laboratories.Because samples have to be corrected for fractionation, the equation is more correctly written as: where AIn the case of samples derived from the terrestrial environment, assumption 3 does not really apply and the other three have been overcome by correlating the radiocarbon dating technique with dendrochronology.The latter has provided a continuous sequence of tree ring material of absolute known age, which covers the entire Holocene.Radiocarbon dating of decadal sequences of this material has provided a plot of true calendar age versus radiocarbon age, i.e. This calibration curve has now been extended back to the upper limit of detection using paired 14C and U-series age measurements on coral sequences, 14C dated high-resolution marine varves, etc.
