Abstract

In nuclear power plant accidents, enormous amounts of radioactive substances are released over a relatively short period of time (several hours to days). The direction and range over which the substances are dispersed and the amount deposited on the ground surface are influenced not only by the amount that is released but also by meteorological conditions at the time of and immediately following an accident. The most important meteorological factors include wind direction, wind speed and precipitation. Whereas wind direction and speed directly affect the atmospheric transport of radioactive substances, precipitation is the predominant factor that controls the removal of these substances from the atmosphere by wet deposition.
