Get Factors Affecting Radiofrequency (rf) Exposure Levels From Mobile...

The threshold level is a SAR value for the whole body of 4 watts per kilogram (4 W/kg). The most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the RF energy is absorbed most efficiently when the whole body is exposed.

RF radiation has lower energy than some other types of non-ionizing radiation, like visible light and infrared, but it has higher energy than extremely low-frequency (ELF) radiation. If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to burns and body tissue damage.

Use airplane mode as often as possible. ... Do not sleep with your cell phone near you. ... Keep the phone away from your body. ... Keep the phone away from your head. ... Avoid products that claim to block radio frequency energy. ... Reduce cell phone use when the signal is weak. ... Remove your headsets when not on a call.

In general, for services below 65 MHz, measurements of both the electric (E) fields and the magnetic (H) fields may be required. ... As a result, measurement locations are usually situated in the far-field region, and in general, only electric (E) field measurements are required.

Cell phones emit low levels of non-ionizing radiation while in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy.

Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).

Some members of the public have attributed a diffuse collection of symptoms to low levels of exposure to electromagnetic fields at home. Reported symptoms include headaches, anxiety, suicide and depression, nausea, fatigue and loss of libido.

The brand of phones they tested that emit the most radiation can put out 1.68 watts per kilogram, as was the case with the 5T from Chinese manufacturer OnePlus. The Federal Communications Commission (FCC) in the United States sets the standard for phones at 1.6 W/kg.

Reduce the amount of time spent using your cell phone. Use speaker mode, head phones, or ear buds to place more distance between your head and the cell phone. Avoid making calls when the signal is weak as this causes cell phones to boost RF transmission power.
