Sunlight between 290 and 313 nm can produce sunburn (erythema) in 30 min. The intensity of radiation between these wavelengths in summer, at 45° latitude and at sea level, is about 5 X 105 W m-2 Assuming that each incident photon is absorbed and produces a chemical change in one molecule, how many molecules per square centimeter of human skin must be photochemically affected to produce evidence of sunburn?
