Enhancing Nuclear Safety
IRSN – Institute for Radiological Protection and Nuclear Safety – is
the French national public expert in nuclear and radiological risks.As a research and expert appraisal organization, IRSN contributes to the implementation of public policies concerning nuclear safety and security and health and environmental protection against ionizing radiation.
IRSN contributes to the safety of existing and future nuclear facilities through a wide range of activities: examining the files submitted by Operators of facilities in operation or under construction, supporting inspection teams from the French safety authority, contributing to the process of updating national and international regulations, developing research programs regarding the prevention of accidents...
With ionizing radiation being found in such wide-ranging applications, radiation protection for workers and the public is an essential aspect of IRSN’s activity.
IRSN is responsible for performing radiological monitoring of the environment throughout France, carries out research and analysis to better understand the exposure of workers exposed to radiation, and works to improve the conditions of patient exposure.
Emergency, post-accident situations
In the event of an incident or accident involving sources of ionizing radiation, IRSN provides guidance to public authorities on the technical, public health and medical measures to be taken to protect the population, workers and the environment, while restoring safety at facilities. IRSN's emergency response center can be called in at all times.
Security and non-proliferation
IRSN contributes to national and international efforts to control nuclear and sensitive materials and protect facilities against malicious acts, through the enforcement of treaties on control of nuclear and sensitive materials, and the escort of international and national inspection teams.

On Thursday, 3rd September 2020, the Director General of IRSN held an exchange with the President of the Federal Office of Radiological Protection (BfS), Inge Paulini, on current issues in radiation protection.
Since the publication of the IRSN information report of June 30, 2020, measurements available abroad have made it possible to model the transport of air masses in Western Europe and to determine a plausible geographic area of the release origin which is located on a territory covering part of the Baltic countries and Western Russia.
Measurements in France from the IRSN’s OPERA monitoring network do not reveal the presence of radionuclides linked to this release.
Jean-Christophe Niel, Director General of IRSN: “The transition and succession will be well assured with this team, which guarantees continuity and the highest level of excellence. I would like to warmly thank Thierry Charles for the expertise he has shared over the years and I salute his entire career and his unfailing commitment to IRSN and nuclear safety.”
The safety and radiation protection authorities of the Scandinavian countries have reported an increase in atmospheric radioactivity detected by their monitoring stations during June.
To date, available measurements from the IRSN’s OPERA monitoring network show no abnormal increase in the level of atmospheric radioactivity in France.
Since the publication of our information report of April 24, 2020, it seems that the fire outbreaks are now extinct. The new information report published today by IRSN contains the latest information available and updates the modeling of the trajectories of air masses contaminated by fires.
Fields of activity
IRSN contributes to the safety of existing and future nuclear facilities, and to radiological monitoring of the national territory and workers exposed to ionizing radiations.
IRSN offers its expertise and services in nuclear safety, human radiation protection and protection of the environment to authorities and industrials across the world.
IRSN is also an active partner in :
IRSN’s research focuses not only on acquiring new scientific knowledge, but also on developing technical tools required to control risks and help expand the Institute's expertise capabilities. These programs are adapted to take into account normative, regulatory, technological, industrial and social issues.
