Low radiation boosts Sony Ericsson

A major survey of mobile phones has put Swedish – Japanese mobile phone manufacture Sony Ericsson on top with their T290i mobile phone. The TOC Development test, which measures radiation levels as well as user-friendliness and other factors, last month gave top marks to Sony Ericsson’s K700i and S700i models.

In this month’s test of five phones only two passed, the other being the 9090 by Qtek. Despit doing well with some of their phones, Sony Ericsson’s K300i was among one of the three phones that failed the test. The other two were the 3230 and the 7270 made by the Finnish mobile telephone producer Nokia.

The test are conducted by TOC Development so that customers know which phones have the lowest radiation and best quality of communications.

So, just how safe are these mobile phones?

“It’s not possible to give a clear answer regarding the effect on peoples health”, says Professor Yngve Hamnerius from at Chalmers University of Technology in Gothenburg. “Different studies give different results.”

Some researchers believe that the level of radiation emitted by mobile phones is too low to cause any harmful effects as the power is not sufficient to break any chemical bonds. However, some researchers consider that there is currently insufficient data to draw any conclusions, and as the effects of radiation can be random it can be difficult to test its effects.

“Unfortunately children where not part of the study. There is some apprehension that children can be extra sensitive to the radiation as their nervous system is still developing. And teenagers are high users of mobile phones”, says Hamnerius.

Experts recommend that mobile phone users err on the side of caution and minimize exposure to mobile phone radiation. This can be achieved by not using the phone more than necessary and by using a handsfree, as recommended by TOC Development.

Using a handsfree could reduce the amount of radiation absorbed by the head by as much as 50%, according to a report from a British on-line service. Also, using the phone on the left hand side of the head is better than the right side as the brain is smaller on the left side than the right side which means it is further away from the radiation source.
