High frequency waves can penetrate objects, walls and other materials. When a person receives these waves like an antenna, electrical voltages and currents flow through his or her body and thus a certain amount of radiation power is also absorbed. This is referred to as coupling to the body. It describes how much of the incoming radiation penetrates the human body and how much of it is absorbed by the body (SpecificAbsorption Rate: SAR).
For all types of parameters, there are measuring devices with which an experienced expert can precisely measure and localise local stress.
In order to avoid damage to persons exposed to radiation, the legislator has specified frequency-dependent limit values for all of these parameters, which must not be exceeded under any circumstances. This implies: the lower the radiation exposure of a person, the smaller the health risk. The Sh radiation protection sleep system contributes to this just as much as all other Sh products, which are explained elsewhere.
I will be happy to carry out the appropriate measurements for you. Let us find out together how your home is doing.
