From Andrew Cook
The National Radiological Protection Board chooses to ignore a considerable body of independent evidence regarding the effects of electromagnetic radiation on natural organisms (Letters, 11 November). The importance of low level background electromagnetic fields (EMFs) to life is emphasised by NASA putting Schumann wave generators on spacecraft, where lack of natural terrestrial EMFs causes immune problems and weight loss. The question is: are some frequency-amplitude electromagnetic windows harmful instead of beneficial?
Two simple studies will very easily demonstrate possible effects of EMFs generated from our electricity supply system. The first is a correlation of households in which someone is or has been a cancer sufferer against distance from substations and power lines. The second is looking for possible variations caused by microwave radar shadows (direct sight and behind hills in undulating topography). Both these could be done as small scale pilot studies in less than one year, given a Geographical Information System and some cooperation between a local health authority, local GPs and a good statistician.
