Good thing kids (and many non-kids) these days text instead of talking on their phones. Any idea if the radiation is decreased when holding the phone in your hand while there is no voice data going in/out? I would assume it is...
Ah, but they hide the phones under their desks, so the teacher can't see them. Hide the phones in their laps. We're breeding a generation of Luddites by allowing phone-using kids to sterilize themselves :)
