Developing technology and industry and increasing application of electromagnetic fields in medicine, threaten the environment and human health. Biological effects of these fields depend on the field magnitude and physical characteristics of exposed tissue. In order to research the effects of electromagnetic fields on kidney tissue on electromagnetic field generator was made with intensities of ...

Background: This study aims to evaluate the negative health impacts of exposure to electromagnetic field and to prepare a risk map of two selected call centers. Materials and Methods: Two call centers whose electromagnetic field values were measured by calibrated low high and point frequency measurement device. The measurements were performed by following the EN 50492 Standards. 178 employees ...
