A COMPARATIVE STUDY OF THE EFFECTS OF ULTRAVIOLET RADIATION ON THE EYE.
Abstract
A fluid transpiration arc (FTA) filled with argon gas was used to produce a high intensity continuous spectrum. Animal and human exposures were made to establish the photokeratitis threshold and abiotic action spectrum. The abiotic action spectrum ranged from 210 to 320 nm. The peak of the ultraviolet threshold curve was at 270 nm for the rabbit and the primate. The rabbit photokeratitis threshold was 0.05 X 10 to the 6th power ergs/sq cm at 270 nm. The primate threshold was 0.04 X 10 to the 4th power ergs/sq cm at 270 nm. The human threshold at 280 nm was 0.05 X 10 to the 6th power ergs/sq cm. Formulas and calculations are given for protection against ultraviolet encountered in the space environment. (Author)
