For mobile communication users it is important to understand that any phone of GSM standard is a receiver and transmitter of low capacity radio signals.
In spite of evident necessity and usefulness of the mobile communication in the life of a modern person there is a certain list of places, where it’s necessary to restrict yourself in using mobile communication, specifically:
- In the hospitals and other health care institutions, where life support equipment is installed and operated. The mobile phone can potentially impact the work of sensitive medical equipment, that’s why we recommend turning off your mobile phone in the hospitals and other health care institutions, where even such insignificant radiation can result in undesirable failures of the medical equipment.
- Most user manuals to mobile phones include a rule about unacceptable use of mobile phone simultaneously with the personal medical devices. If you use any personal medical devices (cardiostimulator, hearing-aid etc.) it is necessary to consult its manufacturer on the safety issues.
- On board of a plane. Radiation from the mobile phone can potentially result in failure of navigation devices. That’s why it is strongly prohibited to use the mobile phones on board of the planes. One should understand that a sign with the crossed mobile phone implies that you have to turn off your phone, and not just reject calls. However, some mobile phone producers provide for a «plane» phone mode in their new mobile phone models. It means that the device «forgets» about its mobile origin and completely turns off the receiver and transmitter.
- It is not recommended to use mobile phones in the locations with potentially explosive atmosphere. They include ship decks, filling stations, and locations with the air containing small chemical particles or metal dust.
