Measurement of Ultra-Low Potassium Contaminations with Accelerator Mass Spectrometry
Levels of trace radiopurity in active detector materials is a subject of major concern in low-background experiments. Among the radio-isotopes, K is one of the most abundant and yet whose signatures are difficult to reject. Procedures were devised to measure trace potassium concentrations in the inorganic salt CsI as well as in organic liquid scintillator (LS) with Accelerator Mass Spectrometry...
متن کاملDetermination of 238Pu, 239+240Pu and 241Am in air filters
The aim of this work is to present the method for sequential plutonium and americium activity determination in air filters using chromatographic radionuclide separation and alpha spectrometry measurement. The developed method may be employed for the purposes of workplace monitoring and as an indicator of the need of introducing the individual monitoring as well as a useful complementation of in...
متن کاملDetermination of ultra-low level 129I in vegetation using pyrolysis for iodine separation and accelerator mass spectrometry measurements
Radioactive isotopes of iodine are themost common radiological toxins from nuclear accidents due to their high release and high enrichment in human thyroid. Among the radioactive isotopes, long-lived I can not only be used for the estimation of the radioactive risk of short-lived radioactive isotopes of iodine to humans and ecosystems, but also for the investigation of the biogeochemical cycle ...
متن کاملSample preparation for quantitation of tritium by accelerator mass spectrometry.
The capability to prepare samples accurately and reproducibly for analysis of tritium (3H) content by accelerator mass spectrometry (AMS) greatly facilitates isotopic tracer studies in which attomole levels of 3H can be measured in milligram-sized samples. A method has been developed to convert the hydrogen of organic samples to a solid, titanium hydride, which can be analyzed by AMS. Using a t...
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...
