Sweden, May 3-4, 2001. The objective was to highlight recent progress and problems for
techniques to study environmental radioactivity. It covered the aspect of detector sample
geometry’s and methods for evaluation of gamma gamma pulse height distributions. Within
the field of alpha-spectrometric techniques gridded ionisation chambers, semiconductor detectors
and a general description for analysis of alpha-particle-spectra were presented. Recent
development in mass spectrometric techniques, AMS (Accelerator Mass Spectrometry)
and ICPMS (Inductively Coupled Plasma mass Spectrometry) for long-lived radionuclides
was described. Principles for analysis of beta particle emitters, especially by liquid scintillation
were presented. The seminar also covered radiochemistry such advantages and disadvantages
between ion exchange, solvent extraction and extraction chromatography. The use
of controlled laboratory conditions for discerning the dynamics of accumulation in organisms
was demonstrated. Other techniques such as neutron activation were also shown to be useful
analytical tool for certain long-lived radionuclides. The results of the intercalibration exercises
within the Nordic countries showed the importance of such analytical quality control. | | Publication date: | 01 Jan 2001 | | ISBN: | ISBN: 87-7893-106-1 | | Number of downloads: | 5030 | | Download: |  NKS-53.pdf |
