THERE are good reasons to resist the installation of smart meters but the alleged hazard of wifi is not one of them, (letters, October 26).

You might reasonably object to the spread of personal information or the possibility of being remotely cut off whether by design, accident or hacking.

But please don’t perpetuate the myths about wifi.

There is no good evidence that wifi can harm DNA – only a couple of discredited studies and anecdotes.

Non-ionising radiation such as used in wifi and mobile phones is far too weak to have any such effect.

And as for the WHO report of 2011, this found limited evidence of a particular form of brain cancer among heavy mobile phone users but could not establish a causal connection.

No other forms of wireless emission were implicated.

The 2b classification implies merely a possibility – compare that with sunlight which is a well established carcinogen but would you want to spend your life in darkness?

It seems some do.

The letter cites a Dr Andrew Tresidder as if he were an expert on the effects of wireless radiation on patients.

Not someone I would look to for good evidence.

Smart meters transmitting 24/7 – well no, actually.

Typically about one or two per cent of the time but never mind about facts.

Of course everyone is free to make up their own minds but do so on the basis of evidence rather than myths.
