Show I Test Ultraviolet Lamps in Schools Control of epidemics of measles, I chickenpox and mumps by the in-' in-' stallation of germ-killing ultraviolet ray lamps in classrooms is being tried on an experimental basis by the New York State department of health. The decision to begin the study with some of the large central rural schools was based on the fact that schools of this type, which are a relatively recent development, have been found to play a major role in rural areas in the spread of the communicable diseases of childhood. child-hood. Tests to determine the bacterial contamination of the air in representative repre-sentative rooms with and without ultraviolet lights will be made. The ultraviolet light intensity and bactericidal bac-tericidal activity of the lamps will also be studied periodically. |
