Description du sujet de thèse
From the 1940s to the 1980s, low- and intermediate-level radioactive waste was dumped into the oceans. In the abyssal plains of the NE Atlantic (-4500m), these operations were concentrated between 1971 and 1982 on two sites that account for over 80% of the waste dumped in the Atlantic, approximately 250,000 barrels. The offshore NODSSUM campaigns (the first of which will take place in June-July 2025) aim to characterize the distribution and condition of the barrels at these two sites and to assess the environmental consequences of the waste.
The doctoral research takes place within the NODSSUM project and includes participation in the second sampling campaign, leading and managing analyses to characterize various environmental compartments (water, sediment, living organisms), interpreting results and contextualizing them, estimating the physical doses delivered to organisms, and studying the transfer and transport aspects of radionuclides.
Required skills: The candidate should have a strong background in radiation physics, environmental radioactivity, and dosimetry. A solid level of proficiency in data analysis and computer programming is essential. Experience in nuclear measurement and Monte Carlo simulation would be significant assets.
Contexte de travail
The thesis is part of the Health-Environment division of LPCA (Laboratoire de Physique de Clermont Auvergne), a Joint Research Unit under the dual supervision of the Université Clermont Auvergne and the Centre National de la Recherche Scientifique (Institut National de Physique Nucléiare et de Physique des Particules). The LPCA's fundamental research activities deal with the ″two infinities″, the infinitely small and the infinitely large, from the most elementary constituents of matter to cosmology. Multidisciplinary activities exploit the spin-offs of this fundamental research or the methods and technologies used. The Health-Environment Division accounts for around a third of the LPCA's human resources. Its members are co-authors of over 100 peer-reviewed publications from 2019 to 2024. Its scientific activities are built on 4 pillars: experimentation, instrumentation, open science and modeling.
