Characterisation of environmental radioactive particles

Control samples produced as 1µm size uranium oxide particles are described for the calibration of the instrumental techniques when applied for the characterisation of environmental radioactive particles. The efficiency of nuclear track methods is demonstrated for the location of hot spots in swipe and environmental samples. Examples of the characterisation in terms of morphology, structure, elemental and isotopic composition of radioactive environmental particles detected in sediments and soil samples from different origin are illustrated. The characteristics of the particles are related with the source term and the release scenarios. Correlation between measurements of bulk samples and particles are given

The European RetD project INSIDER: Focus on Performance anal-ysis and overall uncertainty

International audienceThe EURATOM workprogram project INSIDER (Improved Nuclear Site Characterization for Waste minimization in Decommissioning under Constrained Environment) was launched in June 2017. This 4 year project has 18 partners, and aims at improving the management of contaminated materials arising from Decommissioning and dismantling (DetD) operations by proposing an integrated methodology of characterization. This method-ology is based on advanced statistical processing and modelling, coupled with adapted and innovative analyti-cal and measurement methods, with respect to sustainability and economic objectives. In order to achieve these objectives, the approaches will be then applied to common case studies in the form of Inter-laboratory comparisons on matrix representative reference samples and benchmarking. Work Package 6 (WP6) Performance analysis and overall uncertainty' is in charge of the analysis of the benchmarking on real samples, the organisation of inter-laboratory comparison on synthetic certified reference materials and the establishment of overall uncertainty budget.Assessment of the outcome will be used for providing recommendations and guidance resulting in pre-standardization tests
