Are handphones harmful to unborn babies/pregnant ladies?
Researchers say that Mobile phone users should keep handsets away from their bodies while waiting for a call. The researchers also advise pregnant women and young people to keep their use of mobile phones to a minimum. Unit director Tso Wong Man-yin said radiation emissions were checked during five phases – connecting, ringing, answering, listening and connected, but not talking. Five randomly-chosen models were tested. They included a new miniature model, a hands-free model, a non-hands-free model, a model with a pull-out antenna and a model with a fixed antenna. An additional test was made with a device attached to the antenna to reduce the effect of the electromagnetic field. The results consistently showed the highest radiation during call time. The amount of radiation in this phase ranged from 5.5 micro-watts per square metre to more than 10 micro-watts, which was 20 times the amount released when ringing and listening. Even when the phone was not in operation, the figure was 0.05
