Accelerator Mass Spectrometry at Vera
The Vienna Environmental Research Accelerator (VERA) is a dedicated facility for accelerator mass spectrometry (AMS), operated at the University of Vienna since 1996. The principle of AMS with VERA and the advantage of measuring long-lived radioisotopes by atom counting (AMS) rather than decay counting (ß decay) is described. A brief overview on AMS applications is also presented.
متن کاملQuality of Graphite Target for Biological/Biomedical/Environmental Applications of 14C-Accelerator Mass Spectrometry
Catalytic graphitization for (14)C-accelerator mass spectrometry ((14)C-AMS) produced various forms of elemental carbon. Our high-throughput Zn reduction method (C/Fe = 1:5, 500 degrees C, 3 h) produced the AMS target of graphite-coated iron powder (GCIP), a mix of nongraphitic carbon and Fe(3)C. Crystallinity of the AMS targets of GCIP (nongraphitic carbon) was increased to turbostratic carbon...
متن کاملAccelerator mass spectrometry (AMS) in plutonium analysis
The paper summarizes the results of the 240Pu/239Pu atomic ratio studies in atmospheric fallout samples collected in 1986 over Gdynia (Poland) as well as three Baltic fish species collected in 1997 using the accelerator mass spectrometry. A new generation of AMS has been developed during last years and this method is an efficient and good technique to measure long-lived radioisotopes in the env...
متن کاملAccelerator mass spectrometry for biomedical research.
Accelerator mass spectrometry (AMS) is the most sensitive method for detecting and quantifying rare long-lived isotopes with high precision. In this chapter, we review the principles underlying AMS-based biomedical studies, focusing on important practical considerations and experimental procedures needed for the detection and quantitation of (14)C- and (3)H-labeled compounds in various experime...
متن کاملAccelerator mass spectrometry – from DNA to astrophysics
A brief review of accelerator mass spectrometry (AMS) is presented. The present work touches on a few technical aspects and recent developments of AMS, and describes two specific applications of AMS, the dating of human DNA with the C bomb peak and the search for superheavy elements in nature. Since two extended general reviews on technical developments in AMS [1] and applications of AMS [2] wi...
