Examination of electromagnetic radiation exposure on the baby model

The concept of technology, which is rapidly changing and developing today, has an important place in the field of communication, and with this development various electronic devices (mobile phones, computers etc.) have been used by all ages and professions. In addition to the advantages of these devices, there are also disadvantages depending on the widespread use. In this study, it is aimed to investigate the effects of electromagnetic propagation created by wireless devices at the frequencies they operate on the baby model. The main biological risk resulting from exposure to electromagnetic fields is the increase in temperature in the tissue. Accordingly, it is the Specific Absorption Rate, which is defined as the absorption rate of electromagnetic energy per unit weight. Since it is very difficult to directly measure the SAR value in the human body, a scheme has been created to examine the electric field intensity and the SAR distribution using a package program with three-dimensional electromagnetic analysis software. Electromagnetic distribution on a baby model was examined by applying continuous wave signals at 900 MHz, 1800 MHz and 2.4 GHz frequencies over a half-wave dipole antenna. The electric field intensity at the selected reference points and the SAR distribution of the baby model in the brain tissue; was examined at different positions of the antenna and at different frequencies. Thus, the effects of distance and frequency change at the application point on the electric field intensity and the specific absorption ratio distribution were evaluated.
