We gather information from around the world about EMFs, in order to help the lay person understand this complex issue. We have designed a number of instruments so that the general public can find out what they are exposed to, and have written numerous publications on the latest research, what is understood and what is not known, and what you can do to minimise any high fields you may be regularly exposed to. These, and high quality EMF shielding material (including paint), are sold by EMFields. Powerwatch was formed in 1988 to fight a proposal for a large new electricity substation in Norfolk, England, UK. This was on a greenfield site and was to be built to free up an existing one on a valuable industrial site. The original driving force behind it was Neil Mayhew, a road safety engineer working for Norfolk County Council. The issues included electromagnetic effects on health, appropriate power use and energy efficiency. Powerwatch was commended by the Inspector for its professional and appropriate input to the Inquiry. Around the same time, Alasdair Philips was Newsletter Editor for a group called Electronics and Computing for Peace. He and colleagues had been investigating the claimed (mis-)use of non-lethal electromagnetic weapons by the military, one particular example being the 'zapping' of the women peace protesters at Greenham Common ~ a RAF base being used by the American military as a Cruise Missile base. When they visited the Greenham Airbase they measured microwave beams, amplitude modulated at extremely low frequencies, aimed directly at the women by the US military. Interestingly, this was confirmed to Alasdair by senior Home Office officials at a Mobile Phones and Health Effects conference held in Whitehall, London, in 1996. As well as building up a database of both Russian and American military electromagnetic weaponry literature, it soon became clear that low frequency electric and magnetic fields from power lines and electrical appliances were also suspect of being able to cause, or at least ...
