The RF fields get in the tissues exposed to depths that depend on frequency – until 1 cm at the frequencies used by mobile phones.The RF energy is absorbed in the body and produces tissues heating which is dispersed normally through the thermo adjustment mechanism of the body.
The study of the electromagnetic field affects on the hunam beings was made from the beginning of electrical engineering.A first document, written in 1893 approacjes the intensity of the electromagnetic interactions with the environment, including human beings and animals.
The high demand on the reliability of electronics and the rapid growth of radiofrequency radiation sources have rapidly increased the importance of electromagnetic interference (EMI) shielding due to the interference of radiofrequency radiation with digital electronics.
