摘要

This article deals with the problems, connected with the formation of radioactive deposits in sewage (D.S.). It's shown that the main places of the accumulation of D.S. are the fields of filtration, silty sites and biological pools. In order to reduce the extent of the risk of the secondary contamination of environment we could offer the modernization of the elements of the cleansing structures, the development of refining tehnologies and reduction of mobility of radiocaesium.
