MOBILE PHONE RADIATION AND HEALTH FACTS

Many scientific studies have investigated possible health effects of mobile phone radiations. These studies are occasionally reviewed by some scientific committees to assess overall risks. The most recent assessment was published in 2007 by the European Commission Scientific Committee on Emerging and Newly Identified Health Risks. It concludes from the available research that no significant health effect has been demonstrated from mobile phone radiation at normal exposure levels:

Normal exposure to mobile phone radiation cannot cause headaches or dizziness, nor can it cause brain cancers, neurological effects or reproductive effects.

The World Health Organization, based upon the consensus view of the scientific and medical communities, states that cancer is unlikely to be caused by cellular phones or their base stations and that reviews have found no convincing evidence for other health effects

HEALTH ISSUES OF HANDSETS

Radiation absorption

Part of the radio waves emitted by a mobile telephone handset are absorbed by the human head. The radio waves emitted by a GSM handset, can have a peak power of 2 watts, and a US analogue phone had a maximum transmit power of 3.6 watts. Other digital mobile technologies, such as CDMA2000 and D-AMPS, use lower output power, typically below 1 watt, UVA. The maximum power output from a mobile phone is regulated by the mobile phone standard it is following and by the regulatory agencies in each country

The cell phone and the base station or CELL SITE check reception quality and signal strength and the power level is increased or decreased automatically, within a certain span, to accommodate for different situations such as DISTANCE FROM SITE, inside or outside of buildings and moving vehicles.

Which simply means that it is to the advantage of a user/consumer if they are within a reasonable distance from a cell site.

The health risks (ON-LINE ENCYCLOPEDIA)

Despite extensive research on the subject, there has been no conclusive evidence that using a mobile phone causes long term harmful effects in humans.

Mobile phone antennas, base stations and CELL SITES

There's been a lot of controversy about radio antennas, mobile phone antennas and their emissions causing leukemia and other diseases. (Note it is the actual antenna itself that emits radio waves, not the structure that supports it.) The truth is, there is no conclusive evidence one way or the other, but here are few facts about levels of radiation transmission from mobile phone antennas:

• to get a dose of radiation considered dangerous from a mobile/cell phone transmission antenna, you'd have to be almost touching it

• the antennas don't beam directly down so don't 'blow' radiation directly onto us below and the towers that support the antennas don't emit radiation

• radiation dramatically and rapidly decreases as you move away from the mast - 10 meters away, the dose is 0.1% of what it was at 1 meter away; 0.0125% at 20 meters away and so on, thus a 50 watt antenna has the effect of only 0.6 watt at 20 meters away. In contrast DZRH emits 50 Kilowatt power yet there is no documented cancer case caused by its transmission.
