Since 2017, the Chimie sous Rayonnement-Radiochimie sub-division (SCF/SFP) has been organizing a conference dedicated to radiochemistry, radiation chemistry, and nuclear chemistry.

After the first three successful editions in Strasbourg (2018), in Nice(2022 ), and in Nîmes (2024), the 4^th Rencontres Rayonnement Radiochimie (R3C) will be held in  2026 at the University Paris-Saclay (Orsay). Registrations are now open. You can register via the « Navigation/ My registration » tab and submit your abstracts (maximum 1 page, abstract template (R3C2026_ABSTRACT_NAME.docx) by email for an oral presentation or a poster in one of the topics listed below.
