The limits are typically between 1,000 and 10,000 times more restrictive than the limits proposed in the international safety recommendations. They have their origins in a small study in Austria, which is not supported by any independent scientific confirmation. They were originally adopted as a local policy in the city of Salzburg, Austria.
Measurements done for the Swiss regulator confirmed that you cannot build a mobile network and provide wireless services at the limits recommended in the BioInitiative Report. About 50% of locations were above the limits in the BioInitiative Report and 50% of limits were below that. You cannot operate a mobile network and comply with those limits.
As other speakers have noted, and expert groups representing from the Netherlands, Germany, Australia, and the U.K. have all concluded, those limits are not based on scientific evidence of public health. They do not provide any additional public health protection. What they do is reinforce people's concern, and that is in and of itself a health risk that needs to be addressed.
