What is the SAR value for mobile phones and base stations?
High-frequency electromagnetic fields penetrate the human body at a depth of a few millimetres to a few centimetres. The body tissue absorbs their energy and transforms it into heat. This is called the thermal effect.
How is compliance with the emission limits for mobile phone base stations checked?
In Germany, legally binding framework regulations guarantee that electromagnetic fields – emissions – from mobile phone base stations remain within legal limits. These limits are set out in the 26th Ordinance Implementing the Federal Immission Control Act (Ordinance on electromagnetic fields – Verordnung über elektromagnetische Felder zum Bundes-Immissionsschutzgesetz – 26 BImSchV), which thus provides the legal basis for the operation of all mobile phone networks.
What are electromagnetic fields?
Electromagnetic fields consist of electric and magnetic fields. They are created when electric currents and tensions change, forming an electromagnetic wave that spreads. This wave transports energy.
How strong are the electromagnetic fields of mobile phone base stations?
In order to protect the public’s health from the effects of electromagnetic fields, German legislation has prescribed protection limits for base stations. These limits are based on recommendations by national and international expert committees and have been embodied in the 26th Ordinance Implementing the Federal Immission Control Act (Ordinance on electromagnetic fields – Verordnung über elektromagnetische Felder zum Bundes-Immissionsschutzgesetz – 26 BImSchV).
