Abstract: | Summary The thermal effect due to electromagnetic absorption by human tissues is investigated at different frequencies ranging from
101–1016 Hz. Special emphasis is being considered in the microwave band used in wireless communications of the mobile industry. The
present work examines basically the thermal effect that arises as the duration of exposure to the electromagnetic radiation
and its dosage is increased. Using a computer simulation, a semi-classical model is adopted, were the photon-phonon interaction
is mediated by a homogenous sample of identical elements, which are naturally in harmonic modes of vibration. The phonon lifetime
is also included in this work. These thermal effects decrease with frequency in conformity with experimental results. This
model is then extrapolated to the individual cells of a human tissue and the possible rise in temperature is estimated. |
