Abstract
The magnitude of an acute skin dose of ionizing radiation which produces an abundance of 5,6-dihydroxydihydrothymine (t′) equal to that produced by a plausible daily exposure to solar UV (313±6 nm) is calculated to range from 0.27 krad (winter) to 5.65 krad (summer) in temperate latitudes. Considering the evidence for the possible biological importance of the t′ lesion, and the carcinogenicity of a 1.6 krad acute skin dose of ionizing radiation in one strain of rat, these t′ damage. equivalent doses emphasize the magnitude of the challenge presented by solar UV-B.
