Several sources (including LeFigaro) reported last week that the French Parliament has passed what is described as an environmental legislation. The law, which had been under debate for several years, adds new regulations on the operation, ownership, and sale of transmission equipment.
It covers a broad range of issues, including requiring owners of radio transmitters to register their equipment with the local municipality and forbidding the sale of cell phones without also offering BT ear pieces. This last is intended to keep the non cancer causing EM signal in cell phones away from a user's brain.
The law also forbids the use of Wifi in preschools, and discourages the use of cell phones, wireless cameras, and other tech. Or at least that is what is being reported; I can't find those details in the text of the law (perhaps Google translate is stumbling).
The wireless tech is being banned out of an unfounded and unscientific belief that these wireless signals cause harm. In spite of numerous scientific studies which debunk the idea, and even though cell phones have been in wide spread use for a couple decades without causing a spike in brain cancer (not that the politicians need worry about brain cancer - they weren't using that organ anyway), this law bans the tech from nursery schools - just in case.
And even though one, similar studies conclude that Wifi isn't harmful, and two, it has been widely used for over a decade (including in some schools) without any evidence of harm, it's getting banned as well.
Once again, hysteria is winning out over the facts of the situation.
