The UVB content of 'UVA fluorescent lamps' and its erythemal effectiveness in human skin.

چکیده
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)%.

Background and aims: Compact fluorescent lamps(CFLs) are low-pressure mercury vapor lamps, which are more useful than other light sources. Some studies reported the leakage of UV radiation from CFLs. The aim of this study was measuring of ultraviolet radiation from universal compact fluorescent lamps in Iran. Methods: In this study, measuring of UV radiation of 54 bulb compact fluorescent lamps...
متن کاملDichroic Halogen Lamps - unsuitable as UV lighting for reptiles
Ordinary incandescent lamps (with a tungsten filament) produce no ultraviolet light. Recently a range of lamps which do emit significant and useful amounts of UV light have become available. Specialist fluorescent tubes, compact fluorescent lamps and mercury vapour lamps, all designed to emit UVA and UVB light in varying amounts, are now on sale worldwide. Over the last year, those of us writin...
متن کاملEffects of infrared, blue light and UVA-II on human skin
Knowledge about environmental factors that are aggressive to skin has increased in recent years. Although concern previously focused primarily on UVA and UVB, this has broadened to contain damage from pollution, tobacco smoke, other ambient toxins, infrared light, blue light and UVA-II. This article reviews the negative effects of infrared, blue light and UVA-II on skin. Potential protective a...
