Results of the joint IAEA/EEAE Intercomparison exercise on radioanalytical characterization of NORM samples in the European region.

Naturally Occurring Radioactive Material (NORM) may pose radiological risks across various industrial processes. Characterizing NORM is challenging due to radionuclide diversity, complex material matrices, and the multiple analytical techniques required. This study documents an Intercomparison Exercise (ICE) on the radioanalytical characterization of NORM, organized by International Atomic Energy Agency and EEAE to evaluate participants' abilities to implement appropriate radioanalytical techniques and promote harmonization, thus contributing to ongoing optimization efforts into radiation protection of workers and the public.

Intercomparison exercise on the determination of radionuclides in sediment from the Dudvah River.

This paper reports the results obtained during an intercomparison exercise for the determination of radionuclides in a sediment sample collected from the bank of the Dudvah River. The intercomparison exercise was performed in the context of the programme "Harmonisation of techniques and methodologies for measuring radioactivity in the environment" with a network of laboratories of 10 new European Union Member States and Western Balkans countries. The participants were requested to determine the levels of (137)Cs, (60)Co, (40)K and (90)Sr, and invited to provide data for other radionuclides.
