This booklet clearly describes EMR (electro-magnetic radiation) and RF Radiation in simple terms. He lays out what it is and how it is caused. Without panic-mongering, the author then explains whether devices like iPhones, mobile phones, iPads, tablets, microwave ovens and smart meters can be a health problem, and how to avoid over-exposure if necessary.
