Skin cancer, melanoma, and sunlight.

Recent theoretical studies suggest that the earth's ozone layer which filters ultraviolet radiation may be depleted by a fleet of supersonic transports or by continued use of chlorofluoromethanes. It is now generally accepted that short wavelength ultraviolet radiation leads to the development of skin cancer. In this report we demonstrate an approach to estimating the increase in skin cancer incidence associated with increases in skin cancer incidence associated with increases in ultraviolet radiation. The purpose is to demonstrate the logic used and the assumptions that must be made when such estiamtes are made or cited. We emphasize that such estimates should be considered crude until the many assumptions can be investigated.
