An electronic chip aimed at protecting mobile phone users from radiation hits British stores this summer and inventors say people can stop worrying about the possible risks of this must-have 1990s accessory.

US battery-maker Alexander Technologies said yesterday that mobile phone batteries carrying the EMF (electromagnetic field) bio-protection chip will be available by August retailing at around £25 sterling (€30.38). Britain is the first market for the product and other European countries will follow shortly after. Several studies on the possible dangers of electromagnetic fields emitted close to the brain by mobile phones have stirred public scares in recent months. The British government has launched a new inquiry into possible health risks.

The chip's inventor, Prof Theodore Litovitz, said it had been proven that exposure to electromagnetic fields caused cell-function changes - so-called biological effects - many of which were linked to diseases.

The EMF chip worked by superimposing its own "noise field" on mobile phones' radiations to neutralise the electromagnetic fields and eliminate any effect they may have, he said.
