Ultra-trace isotope research in social and environmental studies using accelerator mass spectrometry

ramses-Vizualizace_bez_nápisůEstablishment of the first AMS laboratory in the Czech Republic – Extension of the CANAM infrastructure in reconstructed building of the former Van de Graaff accelerator on the premises of NPI CAS in Řež.

Accelerator Mass Spectrometry (AMS), the most powerful technique for determination of ultra-trace levels of isotopes (with detection limits of up to 6 orders of magnitude lower compared to decay counting), is still missing in the Czech Republic, although it provides means for excellent research in a variety of scientific and technological disciplines. Thus, data on ultra-trace levels of isotopes can only be obtained in a limited extent in AMS laboratories abroad. To overcome this gap a new AMS laboratory will be established to extend the large research infrastructure of Centre of Accelerator and Nuclear Analytical Methods (CANAM) at NPI under the RAMSES project. The new infrastructure will concentrate on research using 14C, actinide research and cosmogenic radionuclides. In 14C research, it will make possible to achieve the following objectives: determination of 14C for radiocarbon dating in archaeology, climatology and palaeoecology up to 50 thousand years ago, measurement of 14C emissions in the vicinity of nuclear power plants, verification of the fossil/recent carbon content in motor fuels, combustion products, food, pharmaceutics and cosmetic materials. The areas of interest for actinide research are mostly related to the sources of actinides and their behaviour in the environment, screening and monitoring of anthropogenic activities, mainly in nuclear fission fuel cycle, production and testing of nuclear weapons, and illicit trafficking of nuclear materials (Safeguard analyses). Determination of cosmogenic radionuclides 10Be and 26Al will be used as radiometric clocks to establish an absolute time scale for the environmental events of the earlier Quaternary period in biology, climatology, geography and geology, providing knowledge needed for reconstruction of past environmental conditions on the global scale, establishing the rates and types of local- and large-scale processes such as erosion and accumulation, soil development and landscape evolution. These two isotopes are also unique tools for determining of age of meteorites.

Thus, the objective of the project is to enable and perform multidisciplinary research, enlarge the research topics possible to investigate by the establishment of the new AMS laboratory, which will comprise a project for and reconstruction of a building at NPI premises in Řež to house a new, medium type, AMS accelerator (with terminal voltage of up to 1MV) and new laboratories. Next step will be acquiring of the existing procedures for sample (target) preparation for AMS determination of 14C, other cosmogenic radionuclides, namely 10Be and 26Al, and selected actinides. The procedures acquired and/or amended will be used for multidisciplinary applications as given above. In order to accomplish all the above goals, the AMS laboratory will cooperate with four renowned AMS laboratories abroad, which will serve as strategic partners of the project.
