This paper describes the basic principle and experimental arrangement of accelerator mass spectrometer based on 2.5 MV Van de Graaff accelerator, and the concentrations of tritium in the heavy water samples have been determined.
The distributions of cosmogenic nuclide 10Be in the upper and lower salt anils from a core (36.4°N,94.5°E) in the Chaidamu basin,Qinghai,China have been measured using the accelerator mass spectrometer. The comparison of these 10Be results measured on saline and detritus phases shows that the Geochemical behaviour of 10Be is detritusphile.
TiN, Al 2O 3 and 26Al 7+ are selected as target material, carrier and detected ion, respectively. 26Al of the product in low energy fusion reaction ( 16O( 14N,α) 26Al) and the reference saples are measured by Accelerator Mass Spectrometer (AMS). The study result shows that the measurement method is accurate and confident.
The progress and present status of nuclear analysis in CIAENAL are briefly described. The emphasis given to the activation analysis, accelerator mass spectroscopy, nuclear solid state track detector, ion beam analysis and nuclear effect study.
Radiocarbon dating of the pollen concentrate from late Pleistocene syngenetic ice wedges was carried out using accelerator mass spectrometry (AMS) in Seyakha and Bizon sections.
Determination of79Se with accelerator mass spectrometry technique
Genotoxic effects of low-dose exposure to pirimicarb studied with accelerator mass spectrometry
The 14C nuclide was detected using accelerator mass spectrometry (AMS).
The new technique of tandem accelerator mass spectrometry (TAMS) has improved the sensitivity for measurement of several long-lived radioisotopes and certain stable isotopes by many orders of magnitude.
