Abstract
This paper presents a model for the estimation of radiation doses due to long-range transport of airborne radioactive material released into the atmosphere by a reactor accident. The paper includes examples of calculated doses in situations where the weather changes during the transport path. These examples show that changing dispersion conditions, such as rain, may bring about considerable changes in the individual doses. Short-term changes in turbulence, mixing depth and wind speed during the transport path also have a strong influence on doses.
