Explanation of the term IMIS


Radioactivity measurement data

The abbreviation stands for "Integrated Measuring and Information System for the Surveillance of the Environmental Radioactivity (IMIS)". IMIS is an extensive measuring system covering the whole area of the Federal Republic of Germany for the continuous monitoring of environmental radioactivity in all environmental media. Federal and States (Länder) authorities and agencies are involved in this task: Federal Authorities are monitoring the large-scale transport of radioactive substances and their distribution in the atmosphere and water; whilst the States Authorities monitor at places where radioactive substances are deposited and could possibly reach the food chain.

IMIS comprises more than 2000 permanent monitoring stations for the surveillance of the gamma dose rates as well as the activity concentration in the atmosphere, precipitation and waters. In addition the radioactivity in food, feeding stuff and drinking water, but also in waste material and waste water is being determined regularly. All monitoring facilities are connected through a computer based data surveillance system with the Federal Data Center of the Federal Office for Radiation Protection (Bundesamt für Strahlenschutz - BfS) in Neuherberg near Munich, where all measured radioactivity data are collected, processed, documented and forwarded to the Federal Ministry for Environment, Nature Conservation and Nuclear Safety (BMU).

In case of an extensive accidental radioactive contamination of the environment the number of measurements per day are to be increased significantly. Based upon these monitoring data and, in addition, prediction data delivered also via IMIS from the German Weather Service (dispersion prognoses) and the Federal Office for Radiation Protection (radiological prognoses), the Ministry for Environment, Nature Conservation and Nuclear Safety can decide on take necessary interventions and measures and issue recommendations for the protection of the population.  more about IMIS
