Definitions of the various risks of incoherent radiation
Artificial incoherent radiation Luminous hazards- ELV and quantitative evaluation

The LEs are listed in table 3, indicating the organs concerned (eye and/or skin), and the wavelength range. Illuminances E (figure 9) or energetic luminances L (figure 10), to be compared with LE, may need to be weighted by the coefficients S, B and R tabulated in the standard NF EN 62471 and decree no. 2010-750. Weighted quantities are called rms quantities. The maxima of these weighting functions are 1 for S (λ) and B (λ), and 10 for R (λ). These maxima can be used to perform majorizing approximations. Staircase majorizing functions can be used. These overestimates simplify calculations. If the increased emissions do not exceed the LEs, the...
