摘要：High-frequency electromagnetic field monitoring is extremely important for the environment.Recording and continuous observation of the levels of harmful factors and their evaluation should be examined by means of systematic and reliable measurements.The purpose of the present research stems from the need for verification and analysis whether modern phones are safe for users during telephone conversations.The analysis was carried out with the use of two ESM 120 and ESM 140 meters measuring the same devices simultaneously.The SAR (Specific Absorption Rate) describes the energy processes in the biological tissues exposed to electromagnetic fields (EMF).The maximum values recorded by the ESM 140 dosimeter are SAR = 0.5 mW/kg.
