This European Standard specifies procedures forThe measurement or estimation andThe assessment of personal exposures to ultraviolet radiation emitted byThe sun. NOTE 1 According to CIE 17.4 UV-radiation is defined as an electromagnetic radiation with wavelength between 100 nm and 400 nm. Due to atmospheric absorption only solar UV-radiation inThe spectral region between 280 nm and 400 nm reachesThe earth's surface in significant amounts.This European Standard applies to solar UV-exposures when staying outdoors.This European Standard is applicable to workers and toThe general population.This European Standard does not apply to UV-exposures caused by artificial sources, e. g. UV-lamps, welding arcs. NOTE 2 Part 1 of this European Standard deals with UV-exposures caused by artificial sources. NOTE 3 For radiation emissions of products other standards apply, such as CIE S 009 for lamps and lamp systems, EN 60335-2-27 [6] for sunbeds, EN 60335-2-59 [7] for insect killers and EN 12198 [8] for radiation emissions of machinery.This European Standard does not apply to radiation exposures which concernThe retina of the eyes. NOTE 4 Ultraviolet and visible radiation exposures of the eyes may result in photochemical damage toThe retina (this is often calledThe blue light hazard).The associated action spectrum contains mainly visible radiation and only a very small contribution inThe ultraviolet region.The determination and assessment of radiation which may result in a blue light hazard may be done in accordance with part 2 of EN 14255 [20].
