Commission de recherche et d'information indépendantes sur la radioactivité

The Commission de Recherche et d'Information Indépendantes sur la Radioactivité (CRIIRAD - Independent Research and Information Commission on Radioactivity) is a French NGO specialized in radioactivity analysis. It was created in 1986 as an aftermath of the Chernobyl catastrophe on April 26, 1986. It revendicates "being independent from nuclear exploitants, the state and all political parties".

The CRIIRAD has an analysis laboratory, equipped for identification of radioactive contamination (food, water, etc.), which has been delivered the technical qualification certificate by the Health minister. It operates both in France and abroad, and is funded by its investigations (more than a thousand studies since its creation) and its memberships' adhesions. As all other French NGOs, it is regulated by the 1901 law on non-profit organizations.

Among other studies by the CRIIRAD, its investigations on the contamination of the French territory following the 1986 Chernobyl catastrophe are the most known, although it also studied the consequences of the Marcoule nuclear power plant and an atlas of radioactive contamination in Europe and France.
