Analysis of the dispersion of malignant anthrax spores 
in a 50-story tower block after a terrorist act has been carried out. 
A computer model of the aerosol dispersion in the case of intensive 
small-scale convection equalizing the concentration of malignant anthrax 
spores in separate rooms of the building has been developed. The model 
permits predicting the time interval needed for the spores to disperse. 
It has been shown that the release of even a relatively small amount 
of malignant anthrax spores can lead to a dangerous contamination 
of the whole building.
