Definition: | effective irradiance with the spectral irradiance, Eλ, spectrally weighted with the ultraviolet hazard spectral weighting function, SUV(λ) Note 1 to entry: The wavelength range for ultraviolet hazard irradiance is specified in ICNIRP-recommendations as λ = 180 nm to λ = 400 nm. Note 2 to entry: The ultraviolet hazard irradiance is expressed in watt per square metre (W·m−2).
