Use an ear-piece and put it in a bag, make shorter calls or use a landline. These are some of the lessons on how to use a mobile phone that children as young as five will be taught in the classroom. After the Christmas mobile phone boom, 300,000 of them will appear in the classroom prompting concerns about kiddie callers' health. Organisations claim that microwaves from mobiles could affect behaviour or even cause cancer or leukaemia. Edinburgh City Council is taking "precautionary" measures by asking schools to teach children the dangers of mobile phones and how to use them safely. While mobiles are banned in the classroom, "You would have to be burying your head in the sand if you weren't recognising young people have mobile phones in growing numbers," Edinburgh councillor Brian Fallon told The Times: Many parents have bought phones for their children as a safety measure. Leaflets are likely to be distributed to parents and information will be passed to head teachers and staff. ® See also: Follow this link for more mobile phone health scare stuff
