Electromagnetic waves. They are all around us. How do they affect human beings? Which fears could be triggered? Are these fears justifiable? The quantity of electromagnetic waves has greatly increased during the last 10 years. More and more electronic devices work wirelessly and there a lot of mobile networks. I took a look at the people‘s fears, the possibilities of a wireless living and the physical and biological risks and behaviors. For my bachelor project, I decided to create a book about electromagnetic waves in our environment. It shows you where and what kind of electromagnetic waves are constantly present, how they work physically and biologically and it contains stories about people who support the increasing use of electromagnetic waves or are against it.
