title: The UVB content of 'UVA fluorescent lamps' and its erythemal effectiveness in human skin.
abstract: The UVB emission from ten different types of 'UVA fluorescent lamp' has been measured by spectroradiometry. The mean ratio of UVB emission to UVA emission was found to be 0.94 +/- 0.35 (1 SD)%. By weighting the spectral irradiance of each lamp by the DIN standard erythemal curve, the mean erythemally effective UVB emission (normalised to 297 nm), expressed as a percentage of the UVA emission, was 0.076 +/- 0.049 (1 SD)%.
