Smartphones have become indispensable everyday gadgets; the user takes them wherever they go.
"When a user makes a lot of phone calls, he is exposed to a large amount of electromagnetic radiation," Stephan Vinnobal of the German Inside-Handi-D portal said.
The Federal German Radiation Protection Office said mobile phone calls use high-frequency electromagnetic fields for transmitting voice and data. When a user makes telephone calls by mobile phone, part of the power of these bands is absorbed into the head.
The German expert Vinnobal that the radiation arises especially when transmitting signals between the mobile phone and the base station for mobile telephony, SAR rates here is a reference to the amount of electromagnetic radiation from the mobile phone, and measure the amount of absorption (W / kg).
The absorption rates determined in the end indicate the strength of heat generated by the absorption of radiation into tissue, as in microwave ovens. In this type of furnace, food is targeted only by more concentrated radiation, .
The experts added that it is not yet clear whether radiation has negative effects on health, and there is doubt that radiation may be a cause of cancer or infertility. "There are studies that appear regularly to establish the risk of radiation or confirm that Safety ".
Radiation is safe and harmless within its maximum limits; the SAR value of a mobile phone may not exceed 2 W / kg. The Federal Radiation Protection Office confirmed that all mobile phones available on the market are clearly "SAR".
Reduce radiation
The user can reduce exposure to radiation, as those who use the smartphone frequently resort to use handsfree equipment, so that the phone remains away from the head.
In addition to the earphones, which are connected to the phone by cable, there are currently Bluetooth headsets, which have a lower radiation rate than mobile phones.
However, smart phones ready to receive radiation also, so it is better to carry smart phones in a bag away from the head, and when using the alarm function in the smartphone, the device should not be placed next to the bed directly to the head.
For its part, the Federal Radiation Protection Office is advised to use the fixed line when there is a chance to choose between mobile phone and fixed telephone, make sure that the mobile phone calls as short as possible, and avoid using smart phones when the reception is bad; The phone needs higher efficiency and therefore produces stronger radiation.
Children are usually more sensitive to radiation from mobile phones, so experts advise restricting the use of smart phones in children as much as possible.
