U.S. jeans maker Levi Strauss & Co. denied it was playing on consumer fears by launching a line of trousers fitted with "anti-radiation" pockets for mobile phones. The trousers, with a lining which the makers say shields against radiation, are designed by Dockers, a brand name of Levi Strauss. "We're not implying in any way that mobile phones are dangerous. Our intention is not to cash in on consumer fears but provide the consumers with what they want,"Levi's European communicati ons manager Cedric Jungpeter said. The design was the fruit of extensive market research showing that the fashion conscious were also health conscious, Jungpeter said. "The debate is open. Although no study has proved mobile phones are harmful , no study has proved the contrary either,"he added. Worldwide studies into the possible dangers of mobile phones produce often conflicting conclusions. A recent one carried out by Australian researchers over a three-year period showed that radio emissions from mobile phones did not trigger the growth of tumors in mice, and therefore probably did not do so in humans either. And another Australian study concluded cellular phones could foster tumor growth. Swedish research published recently concluded that long-term users of first generation mobile phones faced an up to 80 percent greater risk ofdeveloping brain tumorsthan non-users. But a Danish study last year of 400,000 mobile phone users showed no increased cancer risk.
