Abstract

Abstract Apparatus for treatment of humans with ultraviolet rays has one or more mercury lamps, Xenon lamps or other radiation sources and associated reflectors which establish a high-density radiation field in close proximity to the exit opening or openings. The radiation is filtered so that the body of a person located in the region of the high-density field is exposed only to rays in the range of 315 to 400 nanometers. The heat energy output of the radiation source or sources is sufficiently low to enable a person to stand long periods of uninterrupted exposure to radiation in the range of 315 to 400 nm so that a tanning effect can be achieved as a result of a single continuous exposure for a requisite interval of time. Alternatively, the apparatus is equipped with suitable heat absorbing and intercepting means, especially if the radiation source or sources are high-pressure mercury lamps or Xenon lamps. The apparatus can constitute a table model, a floor model, a ceiling model, a wall model or a combination of these.
