The Future of Radiological Protection
NEA/WKP(2025)8 ¦ English ¦ 31 pages ¦ Date published: 2026
This Nuclear Energy Agency (NEA) working paper explores how forthcoming shifts in society, climate and nuclear science and technology may affect the System of Radiological Protection (SRP) and its primary aim. It reviews sustainability (including SRP alignment with the United Nations Sustainable Development Goals [SDGs]); emerging technologies (artificial intelligence in radiological protection and medicine; small and advanced modular reactors [SMRs/AMRs]; and fusion); new applications (space and maritime nuclear uses; expanding radioligand therapy [RLT]); and emerging hazards (armed conflict), alongside cross-cutting issues such as optimisation, stakeholder engagement and regulatory coherence. The paper concludes that the SRP’s primary aim remains fit for purpose. It identifies areas for refinement: explicitly embedding sustainability within the articulation of the SRP; ensuring flexible, values-aware optimisation that integrates social, economic, and environmental factors; preparing guidance for new reactor types and complex waste streams; advancing fusion-specific dosimetry and regulatory frameworks; addressing gove nance gaps for space and maritime nuclear activities; harmonising practices for rapidly scaling medical RLT; and designing regulatory flexibility for wartime and multi-hazard scenarios. It encourages the International Commission on Radiological Protection (ICRP) and partners to use these insights as inputs to the next SRP review cycle and related international standards work.

Integrated Radiometric and Complementary Techniques for Mixed Contaminants and Residues in Foods: Final Report of a Coordinated Research Project
IAEA-TECDOC-2128 ¦ English ¦ 172 pages ¦ Date published: 2026
The IAEA, in partnership with the FAO, recognizes the food safety challenges faced by Member States, including exposure to a wide range of chemical hazards that can harm consumer health, cause economic losses when standards are not met and disrupt food trade. Previous Coordinated Research Projects (CRPs) focused on individual hazard groups. However, testing laboratories and regulatory authorities identified a need for methods that can detect multiple chemical hazards simultaneously. Such approaches are more cost-effective, simplify analytical work and support national authorities in managing risks associated with combined exposure to different chemical hazards. To address this need, the Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture implemented this CRP. The project developed isotopic, radiometric and complementary techniques capable of simultaneously detecting mycotoxins, pesticide residues and veterinary drug residues. It also developed techniques that use minute amounts of chemicals, reducing analytical costs while safeguarding human and environmental health. In addition, the CRP generated new knowledge that contributes to a better understanding of antimicrobial
Improving the Understanding of Irradiation Creep Behaviour in Nuclear Graphite Models and Mechanisms
IAEA-TECDOC-2125 ¦ English ¦ 284 pages ¦ Date published: 2026
This IAEA publication consolidates the current state of knowledge on irradiation induced creep in nuclear graphite - a key phenomenon governing the structural integrity and lifetime of graphite components in nuclear reactors, such as gas cooled and graphite moderated reactors. Building on the outcomes of the IAEA Coordinated Research Project CRP I3 1019, this TECDOC reviews the underlying physical mechanisms of irradiation-induced creep in graphite, historical and more recent experimental data, existing models, and discusses findings that can be applied to the design of advanced reactors with graphite as structural component and/or moderator. It is intended for technical stakeholders including government officials, researchers and academic staff, and nuclear industry professionals interested in the irradiation creep behaviour of nuclear graphite.
