Note 1 to entry: Luminous radiation refers to optical radiation weighted with the CIE spectral luminous efficiency function for photopic vision,
Note 2 to entry: The use of this term is only reasonable if parts of the optical radiation are in the visible range and thus .
Note 3 to entry: The blue light hazard factor of luminous radiation has unit one.
