Abstract

The dosal sites of 61 Koreans were exposed to increasing UVB doses in the 10mJ/$\textrm{cm}^2$ interval from 10mJ/$\textrm{cm}^2$ to 100mJ/$\textrm{cm}^2$ by solar-simulator, and at the 24hr after UV-B exposure we determined the first MED (Minimal Erythema Dose). For the precise measurements, we peformed the second exposures arround the first MED with 2.5mJ/$\textrm{cm}^2$ interval. The mean MED of all volunteers was 39.6 $\pm$ 15.7mJ/$\textrm{cm}^2$. As the distinction of sex, the means of male and female were 46.9 $\pm$ 18.1mJ/$\textrm{cm}^2$ and 31.5$\pm$8.5mJ/$\textrm{cm}^2$ respectively. According to the classification of skin type by Greiter. F.(1), the percent of skin type I to Ⅵ were 10.9%, 36.4%, 34.6%, 12.7%, 3.6%, and 1.8% respectively.
