blue light hazard irradiance

E_B

effective irradiance with the spectral irradiance, E_λ, spectrally weighted with the blue light hazard spectral weighting function, B(λ)

Note 1 to entry: Blue light hazard irradiance is typically of interest for small sources subtending less than 0,011 rad.

Note 2 to entry: The wavelength range for the blue light hazard irradiance is specified in ICNIRP-recommendations as λ = 300 nm to λ = 700 nm.

Note 3 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 4 to entry: It is essential to specify which actinic action spectrum is used, as the unit is the same for any action spectrum.

Note 5 to entry: The blue light hazard irradiance is expressed in watt per square metre (W⋅m⁻²).

Note 6 to entry: This entry was numbered 17-98 in CIE S 017:2011.
