[en] This 6. ALARA conference was jointly organised by the French Society of Radiation Protection (SFRP) and several professional associations (ABR, AFPPE, ARRAD, ATSR, RAMIP, SFPM, SFR). The conference was the occasion to review all aspects relative to the issues of radioprotection optimization and to its implementation to workers, patients and the public in the nuclear, industrial and medical domains. A particular attention must be given to the application of the ALARA principle in all sectors relevant to radioprotection, especially in a context characterized by: big dismantling works under preparation in the French nuclear park, an increased use of X-radiation in the medical domain - involving both patients and medical personnel, new knowledge concerning the health effects of ionizing radiations, and an evolution of European and international radioprotection safety standards. All these aspects were discussed during these conference days.
