Are cell phones dangerous to children?
by David Harvey VK2DMH on Sunday, September 20th, 2009 | 1 Comment
I’ve heard cell phones are bad for babies or infants. Why is this, and what about devices such as radio or tv top antenna?
Should I keep them away from my baby? And, if these things are indeed dangerous, then what would be a safe distance?

Well yes. Cell phones or mobile phones are a special type of two-way radio, and since they have a transmitter that emits radio frequency signals, it is these transmitted radio waves which can pose some risk to small children. This is because a small child’s skull bones are too thin to shield the brain from the radio signals that get transmitted, even when you are not talking on the cellphone.
However a set-top TV antenna is for receiving and does not transmit. Neither does a set-top antenna, like a metal whip, on a radio receiver. (I am talking about a home AM/FM type radio set used to listen to local news and music. Even a shortwave receiver or scanner that just listens-in.)
But two-way radios and other radio transmitters are a different story. They transmit signals, and these can be dangerous to adults and children, depending on the power of the radio set. It is not a good idea to have your body or your head close to any radio transmitter, such as a ham radio or a CB rig.
