Abstract


The concern about the health risks that wireless technology can provide has grown globally thanks to the growing use of the devices by the population, by the finding that the public exposure to EMFs from the devices can be enhanced by the reflection of the microwave indoors. This paper will assess the distribution of electromagnetic field in a car, in order to provide a basis for future research and to estimate the actual level of exposure to which humans are submitted. There were a number of electrical measurements to determine the electromagnetic field produced by various electromagnetic sources. From the results observed, it is possible to see that, in a car, the exposure of humans to EMF is intensified by the reflection of electromagnetic waves in metallic structures. The observed values do not exceed the values recommended by the regulation, but in the face of scientific uncertainty on this issue, is motivated to continue studying the effect of the reflection of microwaves in closed environments, in order to investigate the possible impacts on health.
