    1011To calculate the human exposure the 3 main exposure model parameters (biologically weighted radiance, human geometry and obstructions) and an array of integration factors are used. The latter one is important for the integration over all solid angles e.g. over all directions of the upper hemisphere. This spatial integration can then easily be done by summation of all final weighted radiance values.

    2425For the calculation of the exposure, the weighted radiances (see polar plot in Figure ??) are integrated over all solid angles (directions). For this, the area of each solid angle d on a unit sphere must be calculated. These dimensionless areas have the unit [sr] and can be understood as weighting factors since not all considered solid angles from the different directions have the same size (see also Fig. 2.5).
