The time dependence of the distribution of the volume 
activity of radionuclides over ground layers is calculated under chemically 
equilibrium and hydraulically stationary conditions and under conditions 
of continuous operation of radioactively hazardous units of sewage 
works. As initial information, a set of data on the hydrogeological 
characteristics and physicochemical properties of the sewage-water 
sediments (SWSs) found at the sewage works of Chechersk and Slavgorod 
is used. The results of the calculations performed are analyzed, and 
the data on the egress of radiocesium from the SWSs found in the sludge 
areas and filtration fields with different bases into underground 
water are presented.
