Over-Exposure Injury by
TO LIGHTS.—Protracted exposure to artificial lights or the Pacing of lights unwarrantably close to the skin may result in severe burns or sunburn. The hazard of such injuries is especially pronounced when the skin is not inured to exposure. Experienced operators protect the closed eyes with pads of cotton or gauze and often use pledgets of cotton over the lips and at the edges of the nostrils when the light is directed to these sensitive parts. When burns of this nature result from heat rays treatment under First Aid, Volume VII, Section 5, will be found applicable. Ultra-violet and similar light rays may also produce “sunburn,” which will require treatment of a similar nature.

Before we consider it in this light, let us first briefly review the nature of x-rays and their position in the great electro-magnetic spectrum.
