Irradiation with ultraviolet germicidal lamps is an effective method for sterilizing operating rooms when they are unoccupied. It is, however. impossible to use them in such a place as ICU where staff and patients are present all the tie because of the harmful effect of ultraviolet on human body. For this reason, a special instrumet equipped wth several germicidal lamps to irradiate floor surface was constructed. We assessed the germicidal effet of this instrument on the floor surface.First we coated the surface of a smooth glass plate with various microorganisms at 25 cells/cm^2. Then the coated surface was exposed to irradiation with this instrument. As a result, bacteria (vegetative form) and C. albicans were killed in 3-4 seconds, and the spores of B. subtilis in more than 10 seconds. Second, we exposed the surface of floors (ICU etc.) to irradiation with this instrument. As a result, this instrument had a good effect on sterilizing floor with 4-second irradiation (better effect with 10-second irradiation). when dust was cleared away fromt the floor. We concluded that this instrument has a good effect on sterilizing the floor by passing it through at an easy pace (equivalent to 4-5 second irradiation).
