| Definition: | effective radiant exposure with the spectral radiant exposure, Hλ, spectrally weighted with the ultraviolet hazard spectral weighting function, SUV(λ) Note 1 to entry: The wavelength range for ultraviolet hazard radiant exposure is specified in ICNIRP-recommendations as λ1 = 180 nm to λ2 = 400 nm. Note 2 to entry: The ultraviolet hazard radiant exposure is expressed in joule per square metre (J·m−2).
