APPLICATION OF DUST-SUPPRESSION TECHNOLOGIES

To ensure radiation safety for personnel involved in the work and prevent formation and transfer of radioactive aerosols, all operations involving radioactive waste extraction and disposition of the old storage facilities were performed using dust-suppression technologies. Various localizing, isolating, and dust-suppressing protective coatings based on polymeric compounds were used in the operations. These polymeric coatings were capable of preventing the spread of radioactive contamination in the form of dispersion aerosols into the environ ment. The protective polymeric coatings were applied to dust-prone surfaces using airless and airstream spraying techniques. The efficiency of using these compounds was controlled by measuring (1) the surface activity of radionuclides in smears taken from the external surface of the coatings applied to the surfaces to be protected and (2) the volume activity of aerosols in the working area air.
