Cell Phone Radiation Research part 1

Getting to the truth about cell phone safety is not always easy.

Nor is it popular.

Using independent labs you can see the real picture of what really is going on in your body.



An independent lab in Australia EMC Technologies investigated the safety of cell phones using Bluetooth or hands free technology for a TV show in Australia called Today Tonight.

In the video Chris Zambounis of EMC Technologies states:


“It is not always made clear, that when you use a phone in your pocket for example, that the radiation levels are much higher than they ought to be.”

“The antenna is usually at the back of the phone, so when it is used at the head most of the energy is transmitted away from the phone towards the base station."

"However if it is used in the pocket, say with a blue tooth hands free adapter, the antenna ends up close to the body and most of the energy is absorbed by the body rather than going to the mobile phone tower.”

Chris Zambounis tested four mobile phones for Today Tonight and it seems the more expensive the phone, the worse the level of radiation it emits.

Today Tonight purchased a cheap phone the:

  • Sage Vodafone 226

And three expensive 3g band mobile phones:

  • Sony Ericsson W910 I
  • Telstra HTC Touch Dual a50
  • Nokia E65

Using a one million dollar robot EMC conducted a test of the electro-magnetic radiation coming out of the phones in the body worn position. Like when you put the phone in a chest pocket or trouser pocket when the back of the phone is facing the body.

The results were astonishing.

On the 1800 Mhz frequency band three of the four phones failed the legal safety limits of 2 watts per kilogram of body tissue.

  • The Nokia E65 tested 3.35 w/kg, one and half times the normal standard (legal Safety Standard is 2 w/kg).
  • The Telstra HTC tested 2.46 w/Kg (legal Safety Standard is 2 w/kg).
  • And the Sony Ericcson W910 I tested 2.16 w/kg (legal Safety Standard is 2 w/kg).

At the 2100 Mhz frequency band two phones didn’t pass.

  • Nokia E65 measured 5.84 w/kg , almost 3 times greater than the safety limit.
  • Telstra HTC measured 2.92 w/kg , one and a half times the safety limit.

The only phone to come under the limits was the cheap Vodafone.

Chris says “These safety standards have been set by world experts, when you use a phone in the pocket the safety limit will be often exceeded.”

Chris Zambounis believes the manufacturers get around their legal responsibilities by recommending a spacing limit between the phone and the body, between 1.5 cm and 2.2 cm. But the guide line is buried in the hundreds of pages of each phone manual.

Cell Phones Recalled Due to Dangerous Radiation Levels

LG has recalled thousands cell phones in Canada. The LG 150 cell phone has been found to produce dangerous levels of radiation, higher than the allowable Canadian limits for safetly.

This is the first time that a cell phone has been recalled in Canada due to excessive radio frequency (RF) radiation levels.

How can you be sure that your cell phone is safe? While it is not really a true indication of safety, it is a good idea to research the SAR of the cell phone you are looking to purchase. The SAR provides some measure of how much radiation a mobile phone produces, and is an accepted standard.

One of the best ways to limit your exposure to cell phone radiation is by using an airtube headset for cell phones, and also by using a cell phone chip.
