Nahgrenzwerte

Nahgrenzwerte are a concept primarily used in German-speaking countries to define exposure limits for electromagnetic fields. The term translates to "near limits" or "close limits" and refers to specific levels of electromagnetic radiation that are considered safe for human exposure at close proximity to a source. These values are set by regulatory bodies and are based on scientific research and recommendations from international organizations like the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

The purpose of Nahgrenzwerte is to protect the public from potential adverse health effects that could arise from prolonged or intense exposure to electromagnetic fields. These fields are generated by a wide range of devices, including mobile phones, Wi-Fi routers, power lines, and medical equipment. The limits are typically expressed in units of power density (e.g., Watts per square meter) or electric and magnetic field strength (e.g., Volts per meter or Amperes per meter).

It is important to distinguish Nahgrenzwerte from other types of exposure limits, such as Ferngrenzwerte (far limits), which apply to exposure at greater distances from the source. The specific values for Nahgrenzwerte can vary depending on the frequency range of the electromagnetic field and the intended application. Compliance with these limits is often a legal requirement for manufacturers and operators of devices that emit electromagnetic radiation.
