Electromagnetic Fields (EMF), UV, Laser and Light

Ultraviolet (UV) radiation, visible light, infra-red radiation and electromagnetic fields (EMF) are all covered by the term “non-ionising radiation (NIR)”.

Ultraviolet (UV) radiation, visible light and infra-red radiation form the high-energy range of NIR that is termed “optical radiation”. Typical sources of optical radiation include the sun, lamps, laser and solariums.

The electromagnetic fields that fall outside the range of optical radiation form the low-energy range of NIR; they are generated mainly through technological means. We distinguish between the following EMF ranges: high-frequency (rapidly vibrating) EMF are found primarily in technologies that transmit information via radio beams. Low-frequency (slowly vibrating) EMF occur in all electrical devices that are plugged into the power grid. Static EMF (which do not vibrate) are found in permanent magnets and in magnetic resonance imaging (MRI) systems for medical diagnostics. Many everyday products, such as electric engines, mobile phones or induction stoves, purposely generate EMF to function, while other products’ EMF, such as those of lamps, are owed to their design but do not contribute to the functioning of the product.

Electromagnetic Fields EMF

The lower frequency range of the electromagnetic spectrum ( 0 – 300 GHz) is referred to as electromagnetic fields (EMF).
