Influence of monochromator bandwidth on the erythema action spectrum in the UV-B region.
The minimal erythema dose (MED) was determined in 10 subjects at wavelengths of 300, 310 and 320 nm using an irradiation monochromator. At each of the three central wavelengths, three determinations of the MED were carried out using full bandwidths at half maximum intensity of 5, 10 and 20 nm. The relative erythemal effectiveness of the radiation for each combination of wavelength and bandwidth agreed well with that calculated assuming photoaddition, or linear additivity between wavelengths.
