A status report on a developement in progress in order to detect Dark Matter particles with NaI crystals is presented. This study is performed in parallel in three underground laboratories (Gran Sasso, Frejus and Mentogou) where the set-ups are efficiently protected from cosmic radiations. Preliminary results are very encouraging and systematic investigations are under way to still decrease the radioactive background in all elements of the installation.
