“…The activity concentrations of 238 -239 -240 pu are all within the confidence interval of the information value. An abnormally high value was obtained for americium in IAEA 375, but Moreno et al (8) give the same result. The results for the Boreon soil samples are given in Table 3.…”

Abstract. The study of an Alpine Wetland presented in this study can bring interesting answers to the problems of the environment management. The determination of the radionuclides in soils and sediments has allowed not only to establish the history of depositions and consequently the origin of the radionuclides, but also to evaluate the various transfers, which took place. The studied elements are plutonium 238, 239-240, americium 241, caesium 134, 137 and strontium 90. The detailed vertical study of sediment core shows the accumulation mode and gives information on the sedimentation rate of the small lake. The study of isotonic ratios allows understanding the origin and the environmental behaviour of the elements. Soil core inventory shows the activity on this region. The evolution of the activity versus the altitude is made.

“…This method was used in samples from nuclear power plants such as spent ion exchange resins and evaporator concentrates (Rodriguez et al, 1997). Besides, combined procedure was used for the determination of 90 Sr, 241 Am and Pu isotopes by anion exchange for Pu isotopes analysis, the selective method for Sr isolation based on extraction chromatography using Sr Resin and the TRU Resin for separation of Am (Moreno et al, 1997). In the radiological characterization of low-and intermediate-level radioactive wastes the separation of Pu isotopes, 241 Am, 237 Np and 90 Sr was performed by anion-exchange chromatography, extraction chromatography, using TRU and Sr Resin, and precipitation techniques (Tavcar et al, 2007).…”

“…The Agency's Laboratories in Seibersdorf have developed a combined procedure [4] for the sequential determination of low-level activity concentrations (0.1 to 1 Bq/kg) of Sr-90, Am-241 and plutonium isotopes in a variety of biological and environmental samples. The analysis of the alpha-emitters is performed by isotope dilution alpha spectrometry using Am-243 together with Pu-236 or Pu-242 tracers.…”

The recent achievements of and perspectives for the IAEA programme on measurements of radionuclides in the environment are reviewed. The programme includes sampling and measurement campaigns for the assessment of the radiological situation in potentially contaminated regions and the establishment of a world-wide network to assist the IAEA in carrying out those assessments. Furthermore the programme includes the different actions pertaining to the improvement of the quality ofradioanalytical measurements in the Member States. In addition to training and assistance in the implementation of quality systems, the programme includes the development, compilation, review and dissemination of radioanalytical methods, the organisation of interlaboratory comparisons and proficiency tests and the preparation, characterisation and distribution of reference materials.
