HB

effective radiant exposure with the spectral radiant exposure, Hλ, spectrally weighted with the blue light hazard spectral weighting function, B(λ)

Note 1 to entry: The wavelength range for the blue light hazard radiant exposure is specified in ICNIRP-recommendations as λ = 300 nm to λ = 700 nm.

Note 2 to entry: This definition is based on the assumption that an action spectrum is adopted for the actinic effect considered, and that its maximum value is 1.

Note 3 to entry: It is essential to specify which actinic action spectrum is used, as the unit is the same for any action spectrum.

Note 4 to entry: The blue light hazard radiant exposure is expressed in joule per square metre (J·m−2).

Note 5 to entry: This entry was numbered 17-101 in CIE S 017:2011.
