Due to a lack of financial resources, we unfortunately have to suspend the import of
any new radio frequency and mobile phone-related articles as of now (November 27,
2017). We apologize for this inconvenience and will keep you informed.
Because we received a large number of inquiries, we set up a bank account to accept
donations. With their aid, we hope to resume, at least partly, the import of newly
published articles to the RF archive of the EMF-Portal. Any contribution is greatly
appreciated. Thank you for your kind support!
In a frequency range between 100 kHz and 10 GHz the specific absorption rate (SAR) is commonly used to describe the energy of the electromagnetic field that is absorbed in biologicaltissue and there mainly converted into heat. The SAR is given in watts per kilogram of tissue (W/kg) and averaged over six minute exposure intervals in appropriate measurements or simulations. During this interval, a balance between the energy input and the heat dissipation in the tissue has been reached. By averaging over different body masses a distinction between the exposure of the whole body or parts of the body (e.g. the eye only) can be made.
