METHOD FOR REMOTE CLEANING SURFACES FROM RADIOACTIVE CONTAMINANTS Russian patent published in 2010 - IPC G21F9/28 

FIELD: chemistry.

SUBSTANCE: flexible net is delivered to the worksite in form of a roll which laid on the contaminated surface by unrolling. Marks are also made on at least one edge of the flexible net in the longitudinal direction. The net is removed by tearing from the surface and rolling it together with the contaminants. The next roll laid after the previous along the marks and covering the said marks. The cleaning film-forming composition used is an aqueous dispersion of a polymer, mainly polyacrylate with viscosity of 12-25 s, with weight ratio of dry substance equal to 38-52 wt %.

EFFECT: use of the disclosed method enables cleaning of a large surface without direct presence of people on the hazardous site.
