Of course, you'll have to ask them, but I'd like to point out to you that among the countries that have recently established a national institute for research on wireless radiation safety is Israel. Israel lives and dies by radar. They use it, they know what it is, and they know that they need to be smart in using it safely.
Other countries are Taiwan and India. India is a high-tech country, and has huge problems. The Indian Council of Medical Research has a major study under way now of cellphone users and health because they think it's a serious public health issue in India. Again, it's a very high-tech country.
Those countries have generally banned advertising with children and cellphones. That's an easy thing to do. Turkey did it. France has done it. The trash-talking babies with the cellphones, which looked really cute, is a horrifying idea for many reasons, which pediatricians and developmental neuropsychiatrists talk about as well. An iPotty, that is a potty with a holder for an iPad, is a terrible idea, yet it exists, and there are plastic baby teething rattle cases for iPhones, as well as iPads.
