The Assembly Government has introduced a new set of instructions to be followed by the youngsters, in particular, while using the mobile phones.

The officials said that although there are no specific justifications on the harmful effects of the use of mobile phones on the health of the users, the warnings have been released as a precautionary measure.

Dr. Tony Jewell, Chief Medical Officer for Wales, said that it is better to take precautions than repenting over it later.

He is thus suggesting the youth to prefer texting over talking directly on phone.

He said, "We don't expect young people to stop using mobiles altogether but there are steps they can take to protect their health for the future".

The officials have sent across a warning message to the kids all over the country, which reads: “When you use a mobile it sends out radio signals close to your head”.

Dr. Jewell said the greater the duration of the call, the higher will be the exposure to the radio waves.

In order to find out any particular harms caused by the prolonged use of mobile phones, the researchers will have to conduct more studies, he said.
