Accelerator 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 کاملIntroduction to Radiocarbon Determination by the Accelerator Mass Spectrometry Method
There are three principal isotopes of carbon which occur naturally C, C (both stable) and C (unstable or radioactive). These isotopes are present in the following amounts C 98.89%, C 1.11%, and C 0.00000000010%. Thus, one carbon-14 atom exists in nature for every 1,000,000,000,000 or (1 in a trillion) carbon-12 atoms in living material. The radiocarbon method is based on the rate of decay of th...
متن کامل4.4 Radiocarbon dating of the Iceman Ötzi with accelerator mass spectrometry
On 19 September 1991 an extraordinary archaeological discovery was made at a high-altitude mountain pass (Tisenjoch, 3210 m) of the Ötztal Alps near the Austrian-Italian border. Two mountain hikers from Nürnberg, Erika and Helmut Simon, after having scaled the Finail Peak (3516 m) that day were on their way back to the Similaun mountain hut (3019 m) located at the lowest part of a mountain ridg...
متن کاملAccelerator 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 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...
