The world's mobile phone industry said nothing has been proved by a Dutch survey suggesting that radio signals for the 3G phones can cause headaches and nausea among the public, reports Reuters. The survey was conducted for three government ministries in the Netherlands. "As the effects are small it is unclear whether they have any health significance," the GSM Association, which represents mobile phone operators around the world, said in a written response to questions. Like the researchers themselves, the GSM Association pointed out that similar surveys needed to discover identical effects before the outcome could be accepted as fact. The Dutch study was new in that it looked at possible health effects from radio base stations, which cover a "cell" area of several square kilometres and transmit signals to mobile phones with an electromagnetic field. Ericsson said it could not draw any conclusions from one study and maintained mobile networks were not harmful. "Our position is that there is no scientific evidence that there are any health problems associated with radio waves from mobile communications," a spokesman said. Siemens said it followed the research with interest. "But we don't comment on individual reports," a spokesman said.
