Just a quick question concerning digital radios. We have a digital clock radio alarm in my bedroom, and I have just bought a digital radio for our eldest daughter. Do they pose any health risk? would a regular radio be a better choice? - Many thanks |

Hi Rebecca
No, either should be fine. It is not clear if you just mean "digital" as in "digital clock readout" and/or (maybe also) digital as per "DAB digital radio".
Bedside digital radio alarm clocks originally got a bad name for producing high EMF levels because they actually had a small electric motor in them that turned the digits!!! Those days are long gone.
Ideally keep all wiring away from touching the bed and do not have a light fastened onto the bed-head. The clock should be on a bedside table and, ideally, at least 50cm from the edge of the bed. Then there should be no problem. Ones with red digits are better for good sleep quality than the ones with white or blue LCD screens that seem to be appearing at present.
DAB digital radios give of more EMF noise than the older FM radio ones. For most people the levels are so low that it is still not an issue, though some very EHS people say that DAB radio receivers affect them badly. We do not like the local radio DAB radio transmitters than are being installed around the UK on telephone exchanges and other such places as they pulse at 10 Hz, a brain-wave frequency. However, that is the transmitter and not your radio receiver.
I hope this is helpful.
