Introduction
The NERC Cosmogenic Isotope Analysis Facility at the Scottish Universities
Environmental Research Centre (SUERC) in East Kilbride was established
in 2004 to provide cosmogenic radionuclide analytical facilities to the
United Kingdom scientific community. Analysis of the long-lived cosmogenic
radionuclides 10Be, 26Al and 36Cl
provided by the CIAF can be used to determine surface exposure ages and
denudation rates on timescales of 103 - 106 years,
which yield fundamental information about rates of landscape evolution.
Cosmogenic nuclide inventories also contribute fundamental information
towards understanding paleoclimates and climate system studies, tracing
oceanic circulation, and assessing natural hazards, which tie into the
sustainability of local, regional, and global economies. These areas
are central to the Strategic Science Themes (Climate System, Natural
Hazards, and Earth System Science) and Research Areas (Earth Science,
Marine Science, and Polar Science) underpinning current and future NERC strategy.
Located on the same site as the Recognised
NERC Accelerator Mass Spectrometry (AMS) Facility at SUERC ,
the CIAF’s
purpose is to produce chemically separated samples for measurement by
AMS and to provide final results from AMS analysis. The establishment
of this facility recognises the rapidly growing demand for cosmogenic
isotope data from researchers in geomorphology, Quaternary science, and
allied areas of the Earth and Environmental Sciences.
Detailed coverage of the technical aspects of cosmogenic isotope analysis can
be found in:
Gosse, J.C. and Phillips, F.M. (2001) Terrestrial
in situ cosmogenic nuclides: theory and application. Quaternary Science
Reviews 20, 1475-1560,
and more specific to CIAF sample preparation methods, in:
Wilson, P., Bentley, M.J., Schnabel, C., Clark, R., and Xu, S., (2008) Stone
run (block stream) formation in the Falkland Islands over several cold stages,
deduced from cosmogenic isotope (10Be and 26Al) surface exposure dating.

A review of geomorphological applications is provided by
Cockburn, H.A.P. and Summerfield, M.A. (2004) Geomorphological
applications of cosmogenic isotope analysis. Progress in Physical Geography
28, 1-42.
CIAF scientific support is generally of a collaborative, rather than
service, nature. The NERC Cosmogenic Isotope Analysis Facility can
currently offer analytical services either for chemical preparation
of samples together with AMS measurement
for researchers with their own AMS sample preparation capability. Currently
there is capability for chemical separation of cosmogenic 10Be
and 26Al in quartz, and for cosmogenic 36Cl in
calcite or basalt. Chemical separation for 10Be from minerals
other than quartz is being developed. AMS measurement can currently
be provided for 10Be, 26Al, and 36Cl. CIAF has an "open-door" policy
for all existing and potential users of its facilities at all stages of their
research projects, and laboratory visits and collaboration are strongly encouraged.
