Recommendations on optimization of monitoring contaminated sewage aimed at enviromental protection agxinst radioactive contamination at minimum cost are presented. The way of selecting water sampling technique depends on water composition stability and flow rate. Depending on the type of radionuclide distribution in the sewage one can estimate minimum frequency of sampling or number of samples sufficient for assuring reliability of the conclusion on the excess or non-excess of permissible radioactive contamination levels, as well as analysis assigned accuracy. By irregular contaminated sewage-discharge and possibility of short-term releases of different form and duration, sampling should be accomplished through automatic devices of continuons or periodic operation.

Efficiency of decontamination measures in settlements contaminated as a result of the Chernobyl disaster (exemplified by the Kiev and Zhitomir Regions) is analyzed. Specific and total expenditures for decontamination of a single farm-stead and of a settlement on the whole are described. Estimation of a decrease in the external equivalent radiation dose of population as a result of decontamination measures undertaken is presented.
