In response to Ian Quayle's letter where he draws from studies quoted by the World Health Organisation (WHO), I wish to point out that the 'double-blinded' studies to which he refers have since been widely discredited. People who had not been screened for electrohypersensitivity (EHS) were subjected to electromagnetic frequencies being switched on and off for short periods of time. My EHS symptoms don't occur the moment a device is switched on. They gradually build up. Nor do they instantly disappear when a device is switched off. This is akin to saying that if you drink a glass of whisky and don't feel drunk immediately and aren't sober as soon as you've finished drinking, then it wasn't the whisky making you drunk!

WHO's International Agency for Research on Cancer classified Radiofrequency radiation as a Group 2B "Possible Carcinogen" in 2011. WHO ignores its own agency's recommendations and instead follows those of the International Commission on Non-Ionizing Radiation Protection (ICNIRP), a group of self-selecting industry insiders. ICNIRP guidelines set exposure standards for high intensity, short term thresholds, not low intensity, long term exposures such as from masts.

One overview of research into the effects of exposure to radiation from masts was published by Levitt and Lai in 2010. It can be downloaded from my website (http://burntbyaphonemast.weebly.com/).

Some residents in Mr. Quayle's village of Fownhope have been campaigning for the installation of a phone mast. I want to help save lives. I think that's more important than having a better phone signal.
