Contamination and radiation exposure in Germany following the accident at the Chernobyl nuclear power plant
[en]The radioactive substances released following the accident at the Chernobyl nuclear power plant were distributed by atmospheric transport over large parts of Europe. Due to dry and wet deposition processes, soil and Plants were contaminated. The ''radioactive cloud'' was first monitored on the 29th of April by near surface measurement stations; by the 30th of April the whole of southern Germany was affected. The contaminated air then spread out in both westerly and northerly directions, resulting in increased airborne radioactivity over the entire country within the following days. Airborne radionuclides were deposited on soil and plants in dry form as well as by precipitation. Locally varying deposits resulted from different activity concentrations in aerosols and very large differences in the intensity of precipitation during the passage of contaminated air masses. Rain fails were particularly heavy in Germany during the time the cloud was passing, especially south of the Danube where on average 2,000 to 50,000 Bq of Cs-137 was deposited per square meter on soil, and in some cases even as much as 100,000 Bq per square meter
