Handphone Safety and Health Effects

Don’t use your phone in your car

When used in isolated environment, phone will have difficulty in reaching the network, so it will increase the power level to reach it. Your phone will have power level higher in the car than in the outside. So, if you are really affraid of phone radiation don’t use it on car or isolated metal area (plane, ship). Car Metal body create Faraday effect, that make radiation bounce back in the room, make it accumulate into greater radiation (just like speaker box, no box will make speaker sound softer).

Greater risk of accident.

Some contry make it illegal.

Don’t use fake batteries

Lithium ion are explosive item, poor manufacturing can make the batteries easily exploded on bend or drop.

Signal Booster

Signal booster can increase phone signal strength greatly. It can also make the phone do not conform to FCC certification anymore, because the signal emitted by phone using signal strength device can have SAR Rating bigger than FCC safety limits.

Using a passive signal booster (the one without electronics) is considerably safe, because it works just like extendable antenna do, and the phone it self still have control over signal gain strength. When using active signal booster, the phone do not have control on how much power to emit in order to reach the network adequately. When the signal booster emit the signal too strong the phone will emit greater radiation than standard, also this will hampering cellular network, making other user hard to connect to network.

Things to consider

Buy handphone with speakerphone capability, use it if you affraid of radiation.

Every cellphone is safe, use SAR rating as guidance to find phone with good reception, don’t use it to consider radiation level.

If you think about light frequency band, you usually use anti UV cream or sunglasses to avoid radiation of ultra violet light which can damage your skin. But many people use high intensity infra red to make their skin tan. Handphone frequency is well bellow infra red frequency, so, direct expose will not damage your skin even with high intensity base station antenna.
