IMIS-Migration: Integriertes Mess- und Informationssystem für Radioaktivität in der Umwelt

Abstract

IMIS ("Integrated Measuring and Information System") is a country wide measuring system, which constantly monitors the radioactivity in all important environmental medi a in the entire territory of Germany. The purpose of IMIS is to keep the radioactive exposure of humans and the radioactive contamination of the environment as small as possible by informing extensively about radioactive data. IMIS gathers data of more than 2000 stationary metering stations that monitor the radioactivity close to soil, in air and in water. Beyond that the radioactivity in food, feeds, drinking water and waste water is determined in laboratory samples. All measured values are stored in 24 country-wide distributed Oracle databases, which constantly adjust their contents by means of replication. With the help of the IMIS Client program users at 72 widely distributed institutions verify, aggregate, visualize and evaluate the measured values. For this purpose IMIS creates business charts, geographical maps and tables, which document the radioactive situation. Condat AG renews IMIS on behalf of the German Federal Office for Radiation Protection up to the end of the year 2002.
