Effects on the human body
Low-frequency fields induce currents in the human body that can have an effect on the sensory, nerve and muscle cells.
The greater the field strength, the more pronounced the effects. However, field strength decreases at increasing distance from the source of radiation.
High-frequency fields heat the human body.
The degree of absorption of electromagnetic waves is a function of the frequency and intensity of the field and the type of tissue. The organs with the least blood flow are most endangered, e.g. the eyes. In contrast, the heart and brain are better at handling heat due to their better blood flow.
Besides obvious damage such as burns, long-term effects are also under discussion, e.g. increased risk of cancer, influences on hormone balance, cell growth and the immune system.
