Bio: Diverse backgrounds in science & technology including encompassing engineering and health sciences. Have in the past been adversely affected by the electromagnetic radiation (EMR). Symptoms included spells of headaches and nausea triggered by relatively short periods of exposure. We have all undertaken in depth studies of EMF including its effects, detection, prevention and reduction of exposure. Constantly looking for better and safer ways to use technology in general and mobile phones, computers and electrical appliances in particular.
