Abstract: The invention relates to treatment of liquid radioactive waste. In a container, with non-radioactive cement compound, which plays the role of radiation shield, a filter with selective sorbent is installed. After establishing the resource of the filter, which is not aimed to be regenerated, with protection (filter-container) on disposal through the filter with selective sorbents, a thin Portland-cement slurry, with water cement ration not less than 10 percent, is pumped for cementing the monolith of the exhausted sorbent.
