Non-ionizing radiation is a collective term for several types of radiation which are not harmful in low dosages and without long-term exposure. Non-ionizing radiation cannot cause ionization in biological systems (body cells), even at very high intensity levels. This is the major difference with ionizing radiation. However, certain effects can arise: Heating or causing electrical currents in tissues and cells.
Exposure to higher dosages or concentrations can, however, be dangerous for humans, such as radio frequency radiation of heat sealers and transmitting equipment, infrared radiation of welding arcs, hot objects and lasers (a laser pen, for example!) and UV radiation of welding processes and sterilization lamps. Even less is known about effects such as fatigue, drowsiness and carcinogenicity. Discussions are running high in this area, for example, when it concerns the safety of mobile phones, GSM masts, radars and the like.
