Fewer and fewer people tolerate the proximity of a device that emits electromagnetic waves. Numerous residents of mobile phone masts list a long list of symptoms for anyone who will listen, such as dizziness, insomnia and skin reactions. Some cannot even touch or use a mobile phone without experiencing a severe burning sensation in the fingers or a terrible headache. Others suffer from the presence of a so-called smart meter of the electricity grid. Radiation sensitivity is a mysterious ailment that is spreading worldwide, forcing even those most affected to isolate themselves in remote areas. Curiously, the scientific and medical communities show no particular concern about this "epidemic". What's more, their claims completely clash with those of the victims. Their symptoms would be a psychosomatic response to the bad reputation of electromagnetic radiation. Should we flee from the waves or flee the information about the waves? Are they trying to hide something more serious? This booklet provides an overview of the research on this phenomenon and allows to form a clearer opinion and contribute to the debate.
