Electromagnetic Fields (EMF), UV, Laser and Light

The sun is the main source of natural ultraviolet radiation (UV radiation). Although natural or artificial UV rays cannot be seen or felt, they have an effect on the human body. UV rays are important for the formation of vitamin D in our bodies, but at certain intensities they can damage the skin and eyes.

Conventional LED bulbs, lighting, screens and projectors do not pose a health risk if used properly. This also applies to sensitive population groups such as children or people with very clear eye lenses.

The use of lasers is becoming increasingly common, from handheld laser pointers and light shows to games like laser tag. However, improper or unregulated use of laser radiation can pose serious health risks, particularly to the eyes and skin. This page provides information on the dangers associated with lasers, the protective measures required under Swiss law, and guidance on how to stay safe during events, public gatherings, and recreational activities involving lasers.

Fact sheets for various appliances producing non-ionising radiation (NIR).

Certain cosmetic treatments use laser beams or light, which may involve risks for human tissue. Treatments using radiation and ultrasound have thus been governed by a Federal Act and corresponding Ordinance since 1 June 2019.
