Airplane mode prevents your device from searching for a wireless signal, eliminating radio frequency (RF) EMF radiation emitting from your device. You can still manually turn on your WiFi processor while in airplane mode, which will emit some RF to connect to the Internet. However, since cellular and Bluetooth signals remain off, your exposure to RF emissions is reduced. However, while RF emissions can be eliminated in airplane mode, Extremely Low Frequency (ELF) emissions still emit from your device, as long as it is plugged in or uses a battery (even when it’s off!).
