摘要:

After the Chernobyl accident large and highly radioactive particles were found in several European countries. Particles > 20 μm in aerodynamic diameter were transported hundreds of kilometres from the plant, and they were sufficiently active (> 100 kBq) to cause acute health hazards. Here, a particle trajectory model is used to identify the areas of large particle fallout. Effective release height of the particles and atmospheric phenomena related to their transport are investigated by comparing particle findings with locations given by trajectory calculations. The calculations showed that in the Chernobyl accident either the maximum effective release height must have been considerably higher than previously reported (> 2000 m) or convective warm air currents may have lifted radioactive material upwards during transport. Large particles have been transported to other areas than small particles and gaseous species. The particulate nature of the release plume must be taken into account in dispersion and transport analyses. Air parcel trajectories alone are not necessarily sufficient for identifying the fallout area of radioactive material.
