A general increase in the use of modern communication technologies, including mobile communication, had a positive, and a negative impact on the high school environment. The aim of this study was to analyse the level of high-frequency electromagnetic field values in the mobile communication band in the school environment. We conducted measurements of parameters of the electromagnetic fields: the electric field intensity, the magnetic field intensity, the power flux density of the electromagnetic field and the specific absorption rate (SAR) between years 2013-2015 at Grammar School of V. Pauliny-Toth in Martin. The tools used for the measurements were the personal monitor RadMan XT ESM-30 and the broadband high frequency field meter Narda 550. Exposure to electromagnetic fields is subjected to specific safety standards and did not exceeded the allowed limits also during our measurements in unshielded spaces. However we found that electromagnetic radiation from mobile phones increased significantly during phone calls within shielded spaces of the grammar school. Statistical evaluation confirmed the rise of power flux density of electromagnetic field in the school with greather schielding, compared to control unshielded spaces. Safe use of mobile devices at schools is an inevitable part of the protection and health support of the citizen's public health.
