Evidence so far suggests that mobile phones aren’t harmful, but long-term risks and consequences are yet to be clarified.If you are concerned, you can reduce your exposure to RF radiation by:

Intensive international research has found no conclusive or convincing evidence that mobile phones are damaging to health in the short or long term. However, in May 2011, the World Health Organization (WHO) classified RF radiation as ‘possibly carcinogenic for humans, based on an increased risk for glioma, a type of brain cancer’.The release of this WHO statement prompted many people to call for a 'precautionary approach' to mobile phone use. Research is ongoing.

The levels of RF radiation from the handset, to which your head is exposed, are around 100 to 1,000 times more intense than exposure from base stations.

While research continues into whether or not mobile phone use causes health problems apart from cancer, no negative health implications have yet been found.Mobile phone use can also have other indirect health effects. For example:

Because RF radiation is a form of non-ionising radiation, it cannot cause cancer. There is no other known biological way that RF radiation could be carcinogenic.

Because mobile phone use is so widespread (it was estimated in 2011 that there were around five billion mobile phone users), public concerns about the possible health effects of mobile phones receive a lot of coverage in the media. Because so many people use mobile phones, medical researchers are concerned that any associated health risks, even small ones, could cause significant public health problems.It is important to understand the risks and possible effects of mobile phone use, and make up your own mind about how you use your mobile phone.

There have been many studies throughout the world on RF radiation and its effects on the body. There is a big difference between a biological effect – an effect on the body – and a health effect.For example, RF radiation from a mobile phone has the biological effect of raising the temperature in a localised area of the brain by a fraction of a degree. This biological effect doesn’t automatically carry any health risks. The human body is equipped to deal with very wide variations in temperature without experiencing harm.

The mobile phone system works like a two-way radio, and includes the individual handset and the base stations. Base station antennae are mounted high off the ground (on a tower or roof) to get the widest coverage. A mobile phone has a radio receiver and a transmitter.When you make a call, your phone uses radiofrequency (RF) radiation via its antenna to ‘talk’ to a nearby base station. Once the base station has received your signal, your call is directed through the landline phone system.Mobile phone base stations emit relatively constant levels of RF radiation. The handsets emit levels of RF radiation that vary depending on three things:

It is estimated that the RF radiation from a mobile phone held against your ear will heat a localised area of your face and, to a lesser extent, your brain, by a fraction of a degree. This is less than the heating caused by, for example, exercise. However, high levels of RF radiation overheat body tissues and cause damage.The Australian exposure limits for RF radiation from mobile phones is set far below the level at which any meaningful heating occurs. All mobile phones in Australia must meet the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) Standard RPS 3, which is enforced by the Australian Communication and Media Authority (ACMA).

Radiation is a combination of electrical and magnetic energy that travels through space at the speed of light. It is also referred to as electromagnetic radiation (EMR).Radiation is classified into two broad groups:

*"Ships Next Day" or "Ships in 24 Hours/Tomorrow" refers to business days and applies to orders placed before 4PM CST (orders after 4PM CST are treated as if placed the next business day). These shipping options are only available within the contiguous United States and includes all products except metal frames, 4ft and larger corrugated plastic, orders over 500 quantity signs, stickers, and some large accessories.

Mobile phones communicate with base stations using radio frequency (RF) radiation. If RF radiation is high enough, it has a ‘thermal’ effect, which means it raises body temperature. There are concerns that the low levels of RF radiation emitted by mobile phones could cause health problems such as headaches or brain tumours.
