ABSTRACT: This paper describes the concept of the digital dialogue in teaching as an efficient way to use the educational potential of smart phones and other Internet of Things’ devices. At the same time, the paper investigates to what extent the non-ionizing radiation caused by the use of these devices is safe for teachers and students alike. Such research is necessary due to the increasing frequency of wireless networks usage. By direct measurements at one vocational high school in Serbia, we have determined strengths of magnetic and electric fields at various points in the classroom during the implementation of the digital dialogue. The measurement results have been compared to national and international standards for safety levels of radiation in electromagnetic fields. It has been determined that the level of radiation according to the standards is far below the critical. Nevertheless, this kind of testing should be constantly renewed and even extended, so that insights into the living and working environment of sensitive facilities such as schools may be provided.

KEYWORDS: digital dialogue, Wi-Fi, routers, smartphones, nonionizing radiation measurements, safety levels.
