Real-time systems for the assessment of the radiological impact of radionuclides released into the atmosphere

This paper reports on real-time systems to assess radiological consequences which are an important tool for decision processes on countermeasures in case of large-scale radioactive contamination of the environment. In the Federal Republic of Germany, an integrated measurement and information system is under development that comprises several networks of stations measuring radiological parameters of the environment. The PARK computer code, which processes incoming environmental activity and dose rate data, analyzes and predicts the present and future radiological situation, and assesses the effects of different countermeasures. There is a similar code (EURALERT) for all countries of the European Communities; it is capable of taking into account different living habits, climatic conditions, and agricultural practices
