Abstract
Summary
Two groups of 48 albino strain C mice were placed directly under the light of two Westinghouse “Daylight” fluorescent lamps for periods of 4 or 6 hours a day, 6 days a week, for one year. The ears of one of the groups were painted with mineral oil before raying to facilitate the penetration of the rays into the skin. Although the total amount of radiant energy applied over the total period was considerable, the intensity of ultraviolet radiations in the 3125 A band was very low. There was no evidence of erythema, or neoplastic changes of the skin, or of irritation of the cornea.
