摘要

FIELD: medicine. ^ SUBSTANCE: invention refers to the field of disinfection of surfaces with ultraviolet radiation and can be used to disinfect the premises of public facilities, transport, furniture and equipment. The method includes pre-spray on the disinfected surface treated with ultrasound for 15 minutes of the aqueous suspension of nanoparticles of titanium dioxide with an average diametre of 23.3 nm at a concentration of 0.5 g/l and the subsequent exposure of the surface with a narrowband germicide ultraviolet radiation. ^ EFFECT: invention enables to reduce time of exposure of surfaces and increase the efficiency of disinfection. ^ 1 tbl, 2 ex
