Monaco, the world's smallest country, now has one the world's toughest RF exposure standards. An ordinance adopted at the end of November requires ambient levels near mobile phone towers not exceed 4 V/m (~4 µW/cm2). For radio and TV towers, the limit is a slightly more lenient 6 V/m. These are about ten times stricter than the limits recommended by ICNIRP. Switzerland adopted a 4 V/m standard for cell towers ten years ago. At the time, the Swiss environmental agency said the standard was an example of the application of the precautionary principle (see MWN, J/F00, p.1).
