Claims (2)

1. Способ очистки поверхности от радиоактивных загрязнений путем обработки загрязненной поверхности водным дезактивирующим раствором с последующим удалением отработанного дезактивирующего раствора, отличающийся тем, что обработку загрязненной поверхности осуществляют в замкнутом объеме дезактивирующего раствора путем воздействия на загрязненную поверхность кавитирующим потоком дезактивирующего раствора, при этом разность между давлением протекания дезактивирующего раствора и статическим давлением замкнутого объема дезактивирующего раствора составляет 40÷60 атм (0,4-0,6 МПа), а обработку загрязненной поверхности ведут при температуре дезактивирующего раствора 18-22°С.1. The method of cleaning the surface from radioactive contamination by treating the contaminated surface with an aqueous decontamination solution, followed by removing the spent decontamination solution, characterized in that the contaminated surface is treated in a closed volume of the decontamination solution by exposing the contaminated surface to a cavitating stream of decontamination solution, the difference between the pressures decontamination solution flow and static pressure of a closed volume of deactivation uyuschego solution is 40 ÷ 60 bar (0.4-0.6 MPa), and processing the contaminated surface is carried out at a temperature of decontamination solution 18-22 ° C. 2. Способ по п.1, отличающийся тем, что после удаления, отработанный дезактивирующий раствор направляют на переработку для отделения радиоактивных механических составляющих загрязнения, а после переработки дезактивирующий раствор повторно направляют на обработку загрязненной поверхности.2. The method according to claim 1, characterized in that after removal, the spent decontamination solution is sent for processing to separate the radioactive mechanical components of the pollution, and after processing the decontamination solution is re-sent to the treatment of the contaminated surface.
