What are the sources of electromagnetic radiation?
Electromagnetic radiation sources can be divided into natural electromagnetic radiation sources and anthropogenic electromagnetic radiation sources. Lightning, sunspot activity, and cosmic rays all produce electromagnetic radiation, which is a natural source of electromagnetic radiation; The artificial sources of electromagnetic radiation mainly include various types of radio equipment, as well as industrial, scientific, and medical equipment (ISM).
Various types of wireless equipment, such as mobile phones, walkie talkies, indoor wireless phones, radio and television transmitters, microwave and satellite communication devices, radars, radio remote controls, as well as microwave ovens, high-frequency eye protection lamps, medical magnetic resonance equipment, helium arc welding machines, radio frequency electric heaters, high-frequency heat exchangers, AC high-voltage transmission lines, conversion switches, motors, generators, televisions, computers, etc., all emit electromagnetic radiation.
What is radiation
Radiation is invisible, odorless, colorless, and can penetrate various substances including the human body. Various household appliances, electronic devices, office automation equipment, mobile communication devices, signal transmission equipment, and other devices will emit radiation around them as long as they are in operation and use. People who work, study, and live in environments with concentrated radiation sources are prone to insomnia, frequent dreaming, memory loss, physical weakness, and weakened immunity. Their cancer cells grow 24 times faster than normal people.
How far away is radiation from us? Radiation is everywhere in our living environment!
