This paper presents a general overview of IRSN research activities for assessing and reducing the risks of airborne dispersion of radioactive contamination during the dismantling operations of nuclear facilities. Four main topic areas are addressed: aerosol source term, contamination transfers, behavior of containment equipment and contamination metrology. Firstly, the various experimental and numerical means involved are presented.
