I'd advise starting with a keypad Nokia, "smart" phone may be a bit advanced....

On a serious level, the scare stories were genuine concerns in that they had to be looked at and investigated. Don't forget, this was a time, only fifteen years ago, where superstition mean't people thought mobile phones in general use, as opposed to faulty, could interfere with hospital equipment, light petrol vapour on the forecourt.

Using their cue from research looking over twenty years of children living in houses under electricity pylons, The Dept of Health accepted a report from Kings that said no evidence supports an issue regarding the phones themselves.

However, a couple of points to ponder;

Hospitals have somewhat reluctantly freed up mobile use, with ongoing concerns over peace and quiet for others. No different from trains but could be 24/7 annoyance! Bear in mind that clinical staff have carried bleepers for years and hospitals with tall buildings have made good money out of hosting mobile masts on their roof.

Before looking at random sparking (loose battery normally) don't forget many people get a shock when touching a car they just got out of. I'd ban nylon clothing before getting around to phones...

Mobile phones affecting children's' development? They certainly stifle social interaction and the need to get out and physically play, a key ingredient in any animal's development. The use rather than the technology methinks.
