Table 1
A list of various sources of electromagnetic fields/radiation influencing living organisms [
7].
| Level | Frequency range | Radiation source |
| Static | 0 Hz |
Earth, video screens, magnetic resonance imaging, and other diagnostic/scientific equipment, electrolysis, welding |
| Extremely low frequency fields | 0–300 Hz | Power transmission lines, home wiring, car electric engines, electric trains and trams, welding devices |
| Intermediate frequency | 300 Hz–100 kHz | Video screens, antitheft devices used in cars, homes, shops, card readers, metal detectors, magnetic resonance imaging, welding devices |
| Radio frequency | 100 kHz–300 GHz | Radio, television, mobile phones, microwave ovens, radar and radio transmitters, magnetic resonance imaging |
