The exposure to the electromagnetic fields is well known phenomenon. During the 20th century, environmental exposure to man-made electromagnetic fields has been gradually increasing as growing electricity demand. Every advance technology is posing the challenges in social behavior and created more artificial sources of exposure to the electromagnetic fields now a day. People are exposed to a complex mix of weak electric and magnetic fields, at home and at workplacesbyvarious ways, like as generation and transmission of electricity, domestic appliances, and industrial equipment, to telecommunications and broadcasting. In general, electromagnetic radiations generated as the byproduct of electricity running in electronic devices. An attempt has been made for the study of some valuable bio-effect of electromagnetic radiations with an application of Phantom model. An approach of specific absorption rate (SAR) distribution has been applied in this model. The present results have been complied with the European and USA standards (EN 50361, IEEE 1528) due to an assessment of dosimetric. A gripping device, DUT (Device Under Test) and software Open SAR were used to measure the transmitted radiofrequency (R. F.) or energy in general absorbed by human tissues. The SAR is a function of the electrical conductivity (?), the induced electric field from the radiated energy (measured in Volt/meter) and the mass density of human tissue. Due to the high sensitivity of the probe, its output voltage is measured without amplification. The electric field probe corresponds to the recommendations of CENELEC (European Committee for the Coordination of Electrical Standards) and ICEEE (the International Committee of Electrical and Electronic Engineers) for measuring electromagnetic fields of cell phones, base stations, and various radiating devices. The DUT handle is constructed of a material with low energy loss and low permittivity. It allows moving axes (X, Y, Z) in all three dimensions (3D) or rotation around the phantom ear for precise positioning of device DUT.The calculated values of specific absorption rate (SAR) distribution were found approximate in order of (15=0.05) grams over per unit grams of human tissue. These results were found within good agreement with others. [ABSTRACT FROM AUTHOR]
