Personal safety is something we are all concerned about, including RF and electromagnetic fields and their effects on safety. There are more and more devices communicating by RF and their use has exploded.
Electromagnetic field is a challenge due to its nature: one can not feel, taste, smell or hear it. We as humans simply do not sense it (at least not until real tissue damage). The most dangerous frequency area to humans is between 30-300 MHz. German company Narda Safety is the absolut number one in this business field and partner to Orbis.
