Info Point
The International Radioisotope Supply Chain Meeting – IRIS 2026 – Venue
The International Radioisotope Supply Chain Meeting – IRIS 2026 will take place in the Hilton Garden Inn Leiden.

Willem Einthovenstraat 3
Oegstgeest, 2342 BH, Netherlands
The Leiden Hilton Garden Inn is located just 15 minutes from Leiden city centre and central station (see Google Maps).
GETTING THERE
Amsterdam Airport Schiphol is just 15 minutes from Leiden by direct train (see Google Maps). Leiden Central Station is one of the ten largest in the Netherlands and offers convenient connections to high-speed rail services to Belgium, France, Germany, and the United Kingdom. The city is also ideally situated between the A4 and A44 motorways, providing easy access to international road networks across mainland Europe and the UK via North Sea ferry connections.
Leiden, the City of Science
Leiden is a historic and vibrant city known for its rich scientific and cultural heritage. Home to the Netherlands’ oldest university and the country’s largest life sciences cluster, the Leiden Bio Science Park, the city is a hub for innovation and research. With its charming canals, centuries-old monuments, and world-class museums, Leiden offers a unique setting for international conferences and is among the top five congress destinations in the Netherlands.

Call for Papers
The IRIS Meeting offers a platform for professionals and organisations working at every stage of the radioisotope value chain to share insights, practical solutions, and forward-looking developments. The goal is to foster exchange between those advancing isotope production technologies and those applying isotopes in medicine, industry, science, and beyond.
We encourage contributions from organisations and individuals engaged in isotope R&D, separation, production, processing, infrastructure development, logistics, regulatory oversight, policy making and end-use applications — across both public and private sectors. Whether your work supports the supply chain of emerging radionuclides for cancer treatment, established industrial sources like iridium-192 and cobalt-60, or advanced reactor and accelerator techniques, IRIS aims to capture your expertise.
We also encourage submissions highlighting the use of radioisotopes in industrial applications such as radiography (e.g. Ir-192, Co-60), gauging and process control (e.g. Cs-137, Am-241), sterilization, radiotracing, well logging, and environmental monitoring. Contributions from equipment manufacturers, service providers, and end-users are welcome—especially those addressing production challenges, logistics, regulatory aspects, or case studies that illustrate the impact and evolving needs of industrial and environmental radioisotope use.
Submissions are encouraged on the following topics:
Targets and Target Management
- Target manufacturing and materials science
- Target design for reactor or accelerator irradiation
- Target stations and handling systems
- Stable isotope production for target enrichment
- Target degradation, recycling, and waste treatment
Separation Chemistry and Processing
- Radiochemical separation techniques:
- Liquid-liquid extraction
- HPLC, ion-exchange, and chromatography
- Isotope enrichment and separation methods:
- ISOL, EMIS, AVLIS, molecular laser separation
- Scaling and automation of processing methods
- Radiopurity and impact on downstream applications
Irradiation Platforms: Reactors and Accelerators
- Neutron activation in research or power reactors
- Fission-based isotope production (e.g. Mo‑99)
- Cyclotron irradiation techniques and targetry
- Photonuclear and spallation methods
- Multi-purpose irradiation facilities and scheduling models
- Ion accelerators
Logistics and Transport
- Transport of sealed and unsealed radioactive sources
- Generator systems (e.g. Ge‑68/Ga‑68, W‑188/Re‑188) for decentralised production
- Container design, shielding, and compliance
- Customs clearance and international regulatory frameworks
- Coordination of multi-national supply chains (just-in-time logistics)
Innovation in Infrastructure
- Hot cell technologies and facility layout
- Equipment for automation of radiochemical separation
Innovation and industrial applications
- RTG
- labelling
- etc …
