The people who worry about health effects of RF radiation from mobile telephone masts are superstitious, ignorant luddites. It is vastly implausible that there could be any effects, on top of which repeated studies have failed to find any.
The idea that they are dangerous is stupid, but there are even more stupid ideas around. Among them is the claim by the mobile phone companies and Ofcom that the existence of a tall metal mast, bearing a distinctive antenna and broadcasting a distinctive radio signal, is a trade secret. That claim takes us way beyond tinfoil hat territory and into serious alternate reality.
It is entirely reasonable for Ian Henton and his fellow tinfoil-clad loonies to demand that the location of masts be made a publicly accessible record. "Commercial sensitivity" is frequently used as a cover for political sensitivity, and this is another example.
