Question:How can you minimise the risks of using a mobile phone?

Use a hands free kit so the phone is not so close to your body while you are using it.

Only use the phone when you have 5 bars for reception. When you have less than 5 bars, the phone actually turns up the power of its microwave transmission to compensate, so you are receiving more microwave radiation.

Use the phone less often and for shorter periods.

Texting exposes you to much less microwave radiation than calling.
