Since the beginning of the 1970´s radiation protection courses were offered by the former Zentraleinrichtung für Strahlenschutz, one of the predecessors of IRS. These courses provide intensive knowledge on radiation protection and on safe handling of radioactive materials and ionizing radiation for radiation workers and health physics officials. These courses are in accordance with German radiation protection regulations (Fachkunderichtlinien zur Strahlenschutzverordnung und zur Röntgenverordnung). They are approved by the Niedersächsisches Umweltministerium (Nds. Mbl. Nr. 32/1992,1293; GMBl Nr. 28/1986, 506). In order to maintain this acknowledgement over times to come, the course programme is continuously actualized with respect to the increasing differentiation of classes of knowledge (Fachkundegruppen) and with respect to the inclusion of the actual status of science and technology.
IRS is putting particular emphasis on the quality of education and an intense examination of the knowledge achieved by the participants. This is manifested also by participation in a "Qualitätsverbund Strahlenschutzkursstätten". By collaboration in the working group "Ausbildung" of the Fachverband für Strahlenschutz IRS is participating in the establishment of quality standards for education in radiation production. This latter work is partially done on request of the German Ministerium für Umwelt und Reaktorsicherheit (BMU).
The radiation protection courses are attended by people from industry, from governmental institutions and from research institutes. IRS is the only institution in Lower Saxony offering those courses according to StrlSchV and RöV to such extend to external participants. The courses are legal prerequisites to become a radiation protection official (Strahlenschutzbeauftragter and -verantwortlicher). During the last decade a continuously increasing number of participants has attended such courses. Since 2005 the numbers of attendees increased by more than a factor of two to presently about 1000 particpants per year. A further extension of the courses with respect to frequency and topics covered is envisaged for the future.
