Phone Radiation non-ionizing radio-frequency

Types of Radiation

Short Waves (SW) – range of frequencies: 1.7 – 30 MHz

Wireless household telephones and microwave ovens – frequency ranges: 5.8 GHz, 2.4 GHz, 800-900 MHz.

Cellular communication networks, analog and digital mobile phones, and marine and aerospace radar.

WiFi and Bluetooth data communication– frequency ranges: 2.4 GHz, 5 GHz and others.

Very High Frequency (VHF) for radio broadcasting - range: 30-88 MHz

Long Waves (LW): frequencies lower than 300 kHz
