Minimize stand-by time to situations only when you must be immediately accessible

4) Keep it away from the body when on stand-by. This is because the body absorbs the harmful microwaves much better than the skull. Therefore don't carry an active mobile phone in a pocket or clipped to the belt. Professor Olle Johanson had a case that developed cancer in the body exactly beneath the place where the mobile phone was clipped on to the belt.

Explanation:

1) Minimize the time you speak. This is because the risk for damage increases the longer you speak. Preferably use the mobile only for very short messages, of a few seconds length, never for several minutes.

2) Minimize the intensity of the irradiation. This is because the risk for harmful damage increases the stronger the intensity. Minimize the exposure of the body to irradiation. Switch off the mobile phone when you don't call.

Avoid calling when the signal is weak (as indicated on the phone screen), because then your mobile will irradiate maximally in order to be able to reach the station.

Avoid speaking in elevators and other confined places, because there the irradiation is especially strong (the metal walls reflect the microwaves and also a much stronger signal from the mobile phone is needed so as to reach out through the shaft).

5) Avoid speaking in busses, trains, trams, subway/underground vehicles etc. A Japanese study found a considerable increase of radiation in trains because the radiation was reflected inside the space due to the metal walls. The same goes for all vehicles.

Hold the phone as far away as possible from the head while calling. The intensity of the radiation decreases rapidly with distance (with the square of the distance). Use a loudspeaker phone, as your headset may not always be available.

In the car, use a hands-free set that enables you to put the mobile phone as far away from the body as possible and most preferably uses an antenna mounted on the outside of the car.

Role Play.

1. Make a dialogue between parents and child. As a father/mother explain your child the harmless of mobile phone. As a child proves that you do not believe to these facts and you cannot live without phone.

Make a dialogue between customer and seller. Choose the most suitable model for you paying attention to safety.
