1.4 Optical radiation
Light is essential for humans. However, in some cases employees may be exposed to too much "light"
during their work, which may damage eyes and/or skin. For this type of situation, the EU Directive
2006/25/EC on artificial optical radiation (1) is intended. This describes what effects can occur and what the
exposure limit values are. The term optical radiation includes the visible, ultraviolet and infrared spectrum.
The term light is a looser term that generally refers to the visible part of the optical spectrum.
Optical radiation is part of the family of electromagnetic radiation (EM radiation). The electricity network
emits EM-fields with a very large wavelength. If we shorten the wavelength, we end up with the long wave,
medium wave, short wave, ultra short wave (FM radio) on TV, GSM, microwave and radar. The following is
the optical area starting with the far infrared. After the infrared, the (fairly narrow) visible area follows,
followed by the ultraviolet, which cannot be seen with the human eye. After the hard UV-C, the optical area
and also the non-ionizing part of the EM-spectrum ends. This is followed by the ionizing region with X-ray,
gamma and cosmic radiation.
