Microwave radiation is odorless and invisible but, depending on its intensity, not without danger in the long run. The high-frequency fields, colloquially known as electro smog, can propagate in waves from the source of radiation, but they can also interfere with the functionality of other electrical devices and affect the human body. Electromagnetic radiation penetrates thin walls, conventional windows as well as roof tiles and the body reacts to these fields like an antenna. The BR16 radiation meter from Trotted can be used to detect microwave emissions from all high frequency equipment operating in the 2.45 GHz ISM band. Ideal e.g. in the household or office.
