Thematic sessions

1. Management of NORM impacted areas, including legacy sites, high-background areas and radon impacted sites and NORMs in drinking water and food: from risk assessment to remediation
Chaired by Sanjay Kumar Jha (BARC) and Jelena Mrdakovic Popic (DSA) 

This session focuses on the topic of managing areas affected by Naturally Occurring Radioactive Materials (NORM). NORM encompasses multiple aspects in this session, including legacy sites, high-background areas, sites impacted by radon as well as drinking water and food. The focus extends from comprehensive risk assessment to sustainable and effective remediation strategies, considering the concept of circular economy and possible reuse of NORM waste. Insights on the dynamic interactions of NORM with the environment and human health are also welcome.

2. Radioactive waste management and disposal
Chaired by Joanne Brown (IAEA) and Julia Carpenter (ARPANSA)

This session is dedicated to the impact of radioactive waste management and disposal on humans and the environment. It serves as a forum for the exploration of challenges, innovations, and best practices in handling radioactive waste from the different waste categories (including LLW, ILW, VLLW, HLW, SNF). Within this session, experts, researchers, and practitioners will share their insights into the latest advancements and strategies for the safe and sustainable management of radioactive waste. Topics covered will encompass the treatment, storage, and ultimate disposal in surface or deep ground with a focus on the behavior and transfer of radionuclides in the environment and impact on humans and the environment.

3. New development on measurements and metrology
Chaired by José Marcus Godoy (PUC-Rio) and Filip Vanhavere (SCK CEN)

This session deals with relevant innovations and methods in the field of metrology. Rapid methods and more sophisticated analysis and measurement techniques, as well as in situ measurements, are concerned. Advances in sampling, data processing, computer applications, laboratory facilities and field monitoring techniques are welcomed. Various types of quality assurance issues are important in metrology and also part of the scope of the session.

4. Emergency preparedness and revitalization: lessons from the past and current world events 
Chaired by Olivier Isnard (IRSN) and Hirofumi Tsukada (IER-Fukushima University)

Recent events on Ukrainian territory have triggered a complex, multi-faceted crisis that require the utmost attention in terms of emergency preparedness and response. This session presents an invaluable opportunity to assess the effectiveness of the preparedness and response strategies deployed to mitigate the impact of this crisis. Additionally, it serves as a platform for discussing the crucial task of environmental restoration following nuclear and radiological disasters. Topics to be addressed encompass decontamination measures and the reduction of activity concentration of radionuclides, drawing insights from lessons learned in the past and current world events. Indeed, the significance of preparedness takes center stage when reflecting on the aftermath of events like Chernobyl and Fukushima. Of outmost importance is the active exchange of knowledge and insights among decision makers, practitioners, stakeholders, and the scientific community. Participation from each of these diverse communities is critical and particularly welcome.

5. Effects of radioactivity on the ecosystems: from a mechanistic understanding to a holistic approach of radiation protection
Chaired by Rodolphe Gilbin (IRSN)/(ALLIANCE) and Carmel Mothersill (McMaster)/(IUR)

The session will focus on mechanistic understanding of the processes inducing radiation effects at different levels of biological organization, including the consequences on ecosystem integrity. It includes multigenerational responses, hereditary effects, adaptive responses, genomic instability, and epigenetic changes, as well as effect of co-stressors. New approaches of upscaling from molecular mechanisms of effect to impact at populational level are of particular importance, as well as approaches allowing to encompass all aspects of radiation protection at the ecosystem levels (conservation of biological diversity, ecosystems structure and functioning, both for their intrinsic value and because of the key role they plays in providing the ecosystem goods and other services upon which we all ultimately depend).

6. Understanding and modelling radionuclide mobility and bioavailability in the environment
Chaired by Laureline Février (IRSN) and Mathew Johansen (ANSTO)

Assessing radiological impact of radionuclide releases in a realistic way relies on a good understanding of their distributions in the environment, from their dispersion and transfer in the atmospheric, aquatic and terrestrial media up to their uptake and accumulation in biotic organisms. The session will focus on new experimental findings, as well as development of models able to describe and predict these transfers in different contexts (from short-term after a release to long-term scenarios). All types of models, from conservative assessment models to more detailed research models are welcome.

7. Consequences of global changes on radioecology
Chaired by Mathew Johansen (ANSTO) and Olivier MASSON (IRSN)

This session looks at the relationship between global changes and the field of radioecology. At a time of profound transformations in our planet's climate, ecosystems and human activities, it is becoming increasingly important to understand how these changes may affect either directly or indirectly (by affecting the ecosystems themselves or their functioning) the distribution and fate of radionuclides in the environment, as well as their effect. The evolving methodologies and tools that are enabling us to adapt to these challenges will also be discussed.

8. Advancing radioecology with artificial intelligence and Big Data
Chaired by Olivier Radakovitch (IRSN) and Trevor Stocki (Radiation Protection Bureau - Health Canada)

This session looks at the cutting-edge crossroads of radioecology and advanced technologies. Artificial intelligence (AI) and Big Data are transforming the understanding of radioecology, and this session will explore the dynamic role of these technologies in advancing our knowledge; and how these innovative tools are contributing to more precise risk assessments and informed decision-making in the nuclear industry and environmental science.

9. Fostering engagement between radioecology and society: promoting communication and citizen science initiatives
Chaired by Thierry Schneider (CEPN)/(ICRP) and Yevgeniya Tomkiv (NMBU)

This session seeks to promote trust, understanding, and engagement among radioecologists, the nuclear industry, policymakers, and the public through the promotion of effective communication, transparency, and citizen participation. It will promote actions regarding improved communication, collaboration, and the active involvement of citizens in understanding and addressing radioecological issues, making the session an important and timely topic in the context of environmental and nuclear science. Development of innovative approaches and methods to facilitate the exchange of essential information between various entities, including governments, industry, and the public are welcome.
