Nokia Patents Cancer Shields

Nokia, the world's biggest mobile phone maker, has applied to patent a device that its patent application suggests could counter any risk of brain tumours from electromagnetic radiation from mobile phones.

The application filed by the company in the U.S. first in 1998 said it had been suggested that continuous exposure to radio frequency irradiation could lead "to a development of malignant tumour".
It application said the invention would reduce the irradiation of the user, "especially the brain and the nerve tissues".
Patent
According to a report in The Times, the main handset manufacturers have lodged patent devices to control radiation while continuing to reject claims that mobile handsets are a health hazard. The Times said Nokia, Ericsson and Motorola, the world's three biggest mobile phone makers, had all invented components to shield users from radiation emissions, The Times said. Nokia, in a statement, said its products complied with regulatory requirements and therefore didn't need additional features to counter radiation. It added that it applied for all sorts of patents.

"Patenting innovations is standard practice for all aspects of technology within the industry and antennas are no exception to this rule," it sad. "Nokia has many patents in a broad portfolio, and does not by any means use all ideas in its products."

Ericsson spokesman Mikael Westmark was quoted as telling The Times: "Given the available scientific evidence, there is no link between mobile use and negative health effects". Numerous reports of the health hazards from using mobile phones have circulated in the past decade, but opinion among scientists is divided. Some studies report no link between cancer and mobile phones while others suggest there may be a danger to health. A British government study found no link but suggested young children shouldn't use mobile phones.

However, the patent applications show that manufacturers have been working on radiation-reducing components for a number of years, although the companies maintain that there is no contradiction between the patents and their public stance.
  The patents will be used as evidence in a number of U.S. lawsuits against mobile phone operators such as Vodafone, the Times report said.
