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 کاملSize-fractionated plutonium isotopes in a coastal environment.
We have examined the distribution of individual Pu isotopes (239Pu, 240Pu, and 241Pu) in seawater from the Gulf of Maine (GOM). Samples were size-fractionated with a 1 kD cross-flow ultrafiltration (CFF) membrane. Subfractioned samples were radiochemically purified and Pu isotopes were analyzed using a three-stage thermal ionization mass spectrometer (TIMS). To our knowledge, this is the first ...
متن کاملRapid method for the analysis of plutonium isotopes in a soil sample within 60 min.
A rapid method for the determination of Pu isotopes in a soil sample within 60 min of starting sample pretreatment was developed. The large reduction in the analysis time was attained by the rapid and perfect digestion of the sample using an alkaline fusion method with an induction heating machine. Pu concentrations were then determined by flow injection/ICP-MS using a solid extraction resin af...
متن کاملRelease of plutonium isotopes from the Fukushima Daiichi Nuclear Power Plant accident
The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident has caused serious contamination in the environment. In this work, we summarize and analyze published studies related to the release of Pu from the FDNPP accident using environmental sample analysis and ORIGEN model simulation. Our analysis focuses on several aspects: first, the investigation of the distribution of Pu isotopes derived f...
