Hidden health risks of handphones 


Mobile phone firms have been accused of concealing warnings about the health 
risks of using their handsets.

A warning that Apple's popular iPhone should be kept at least 15mm away from 
the body is buried deep inside the manual. the Daily Mail of UK reported.

BlackBerry goes even further, saying customers should use their devices 
hands-free or keep them an inch from the body "including the abdomen of 
pregnant women and the lower abdomen of teenagers". Again, this advice is 
hidden in the instruction booklet.

All other manufacturers, including Nokia and HTC, carry similar small-print 
warnings despite insisting that holding mobiles against the ear and head is 
harmless.



Health campaigners and politicians on both sides of the Atlantic are calling 
for clear warnings to be put on handset boxes.

They are also demanding a public education campaign, starting in schools, to 
advise on the safe use of the devices.

Alasdair Philips, of Powerwatch, an independent group which investigates the 
safety of mobile phones, said: 'Most people have no idea about these warnings.

"The safety advice should be included on the boxes and far more prominently in 
the "getting started" section of user guides and not just in the detail at the 
back that hardly anyone reads."

"This should be only part of a much wider public education campaign that begins 
in the schools."

The safety advice in manuals is designed to limit so-called Radio Frequency 
exposure. This is said to heat body tissue and some - inconclusive - research 
suggests it is linked to tumours in the brain, Daily Mail reported.

Most RF exposure comes from the antenna and it can increase when a phone is 
kept in a pocket because phones increase their power output when a network 
signal weakens.

Men who carry handsets on their belt or in their pockets with the keypad facing 
outward will suffer higher exposure because the antenna, which is always at the 
back, is close to the body.

SAR - Specific Absorption Rate - is the standard industry measurement for the 
amount of RF energy the body absorbs.

Mr Philips said: "When a phone has to power up, it sends high SAR power into 
the trunk and towards the kidneys and liver. It can be the testicles if in a 
trouser pocket.

"Some girls carry them in chest bags which hang just below their breasts. 
Breasts, eyes and testicles absorb external RF energy the most. Blood-rich 
organs, such as the liver, kidneys and heart are among the top energy absorbers.

"The ovaries and foetus are relatively well protected by the trunk, but it 
obviously makes sense to keep the handset away from those areas, especially the 
foetus in the first six months. Many later-life causes of ill health are 
increasingly being recognised as having their roots in foetal exposure to 
chemicals, hormones, radiation of various sorts."

He said most handsets also put out pulsed ELF magnetic fields which travel 
further into the body than RF signals. These are associated with childhood 
leukaemia and some adult cancers.

Caroline Lucas, Green Party leader and MP, said: "Greens have never said don't 
use mobile phones, but we have always said that as with any other technology, 
we need to make people aware of any potential risks and give clear guidance 
regarding the safest possible use, so we can get the maximum benefit from the 
technology with the least possible risk."

Mobile phone firms are legally required to advise customers on how to minimise 
RF exposure and use their manuals to do so.

Michael Milligan of the Mobile Manufacturers Forum said: "A mobile phone can 
always be used up against the head without the need for this separation, 
because phones are designed to have the antenna far enough away from the head 
when making a call.

"Every mobile phone model is tested to make sure they meet national and 
international exposure limits for exposure to Radio Frequency emissions, before 
they can be sold in the UK or elsewhere."

However, many new phones are so slim, antennas will be closer to the head than 
distances recommended by many manufacturers.
