The DGAC (Civil Aviation Department) implements the policy defined by the Minister in charge of transport in the various domains included in civil aeronautics: design, maintenance and operation of aircraft, aeronautical training, air transport, airports, environmental protection. It prepares the regulations, and sees to their application. It provides airline companies with the services needed for the proper bleed scheduling of air traffic. The DGAC is, first and foremost, the guarantor of French air transport safety. Its involvement in S.I.E.V.E.R.T. : the DGAC makes the SIEVERT system available to airline companies and passengers, and provides the coordination of the actions of its partners.
The IPEV (French polar Institute - Paul-Emile Victor) is the French agency that supports and provides suitable logistics to the research and technology programmes being undertaken in the polar regions by the main French scientific bodies (CNRS, University, CEA...). The Polar Institute is a public interest grouping of public or semi-public bodies, including the Ministry in charge of research, the Overseas Ministry and the CNRS. This grouping was created in 1992 by the merger of the research mission of the French South Pole and Antarctic missions and the French polar expeditions. Its involvement in S.I.E.V.E.R.T. : the Institute provides the data needed to assess solar activity, by means of neutron monitors installed on Terre-Adélie (Antarctica) and on the Kerguelen Islands (Indian Ocean).
The Institute for radiation protection and nuclear safety was born out of the 2002 merger of two bodies, the IPSN (Institute for nuclear protection and safety) and the OPRI (Bureau for protection against ionising radiation). Whether on its own or in collaboration with its foreign counterparts, the Institute for radiation protection and nuclear safety carries out research, studies and assessments on all aspects of the risks related to the use of radioactive materials and natural radioactivity. These missions are notably intended to protect both man and the environment, and to ensure the safety of nuclear installations and of the transportation of radioactive materials. In France, the IRSN centralises, retains and employs all of the data relating to individual exposure to ionising radiation and radioactivity, whether this involves persons exposed in a professional setting or the general population. Its involvement in S.I.E.V.E.R.T.: The institute hosts and operates the system. Each month, it supplies and verifies the data needed for the calculation of the doses of cosmic radiation. The IRSN centralizes and retains the personal information relating to the exposure of flight personnel.
The role of the Paris Observatory is to contribute to the knowledge about the Universe, to provide the national and international community with services related to its research activity, to contribute to initial and continuing education, to take part in the dissemination of knowledge and to implement international cooperative efforts. Its involvement in S.I.E.V.E.R.T.: the Observatory works with the IRSN in assessing the radiation doses. It holds the scientific responsibility for the IPEV's cosmic radiation observation programme, which includes both galactic cosmic radiation and solar flares.
The GSF-National Research Center for Environment and Health is a German Institute that focuses its research on the health of man in the environment. The aim is to identify health risks posed by environmental factors, to elucidate mechanisms of disease development, and to develop concepts for the protection of human health and the natural basis of life for now and the future. Its involvement in S.I.E.V.E.R.T. : The GSF provides each month to IRSN a specific globe map of dose rates calculated using the EPCARD (European Program Package for the Calculation of Aviation Route Doses) computer program. This map of doses is inserted in the S.I.E.V.E.R.T system.
