Laboratory for studies and expertise on radioactivity in the environment (LEREN)


The Laboratory for studies and expertise on radioactivity in the environment (LEREN, ex-LERCM) is located on two sites, Cadarache and La Seyne sur Mer, both in the south of France. This laboratory was formerly the Laboratory for Continental and Mediterrannean Radioecological Studies. It is directed by Christelle Antonelli.

 

 

Summary

 

 

 

Context and research themes

 

LEREN studies the behavior of radionuclides, particularly in the continental environment of metropolitan France and in the Mediterranean marine environment.

 

 

Research axes


The laboratory's chief concern is to observe spatio-temporal variations in environmental radioactivity based on the use of:

     
  • the OPERA network (environmental radioactivity monitoring network)
  •  
  • and studies conducted in nineteen EDF nuclear power plants under an IRSN-EDF agreement.
 

 

These observations provide the foundations for a conceptual framework for assessing the radioecological sensitivity of the environment exposed to authorized routine or accident-related radioactive release.


Lastly, LEREN meets the demand for expert surveys from the public authorities, local authorities and citizens' associations.

Partnership and research networks

 

The network of environmental radioactivity monitoring observatories (OPERA) was set up to provide a regularly updated spatio-temporal reference indicating the activity levels of the main radionuclides found in the atmosphere, river water, and certain bioindicators and food products collected in France.

 

The network covers all of France and the surrounding marine environment (Celtic Sea, Bay of Biscay, Channel and Seine estuary, North Sea, and Mediterranean, in particular the Gulf of Lions and the Rhone delta).
