A group of frequencies at the very top of the spectrum of extremely low electromagnetic frequencies in the Earth’s electromagnetic field are known as the Schumann resonance (or resonances). Global electromagnetic resonances known as Schumann resonances are triggered by the electrical discharge of lightning in the space between the ionosphere and the Earth’s surface. In the modern world, radiation safety is a crucial component of both society and personal responsibility. There should be as much awareness as possible about the potential harm to health caused by excessive exposure to electromagnetic radiation. read more
