DSA - Norwegian Radiation and Nuclear Safety Authority

Norwegian Radiation and Nuclear Safety Authority (DSA) is the national authority and expert body in matters concerning nuclear security, radiation use, natural radiation and radioactive contamination in the environment.
DSA carries out assignments on behalf of the Ministry of Health and Care Services, the Ministry of Foreign Affairs and the Ministry of Climate and Environment. In addition to our national mandate for safety, security, and safeguarding, we have international tasks related to promoting radiation protection, nuclear security, nuclear safety, disarmament and non-proliferation.

We are the responsible agency and expert body for nuclear security, for all use of radiation, for natural radiation and for radioactive contamination of the environment.

We chair and serve as the secretariat for nuclear preparedness in Norway and are the point of contact for reporting national and international nuclear events.

We are the national reference laboratory for units of measurement related to radiation and radioactivity. We participate in the Centre for Environmental Radioactivity (CERAD), which has been designated a Centre of Excellence by the Research Council of Norway.
