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.

Following a visit from a World Health Organization (WHO) delegation end of 2021, IRSN has been reappointed as a collaborating center for its fourth four-year term.
In accordance with its missions in the “Code de la santé publique” (French Public Health Code), the French Institute for radiation protection and nuclear safety (IRSN) periodically analyses the exposure of the French population to ionising radiation due to diagnostic medical imaging procedures.
IRSN is currently participating in the preliminary review of the safety options for the NUWARD™ project by the French (ASN), Finnish (STUK) and Czech (SUJB) safety authorities with the support of their technical safety organizations (TSO) respective ones, including IRSN for France.
Assessing, researching, protecting, anticipating, and sharing: these are IRSN's missions at the service of public authorities and the population. Discover the main strategic directions and projects that have marked our year in the 2021 annual report.
The European Partnership for Radiation Protection Research will contribute to improving the protection of the public, workers, patients and the environment from environmental, occupational and medical exposure to ionizing radiation.
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’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.
