Intermediate-frequency magnetic field measurements in urban public transport vehicles (trams, trolleybuses, and ICE buses) – Bratislava, Slovakia

This dataset contains spatially resolved measurements of intermediate-frequency (IF, 9 kHz – 30 MHz) magnetic flux density collected in a fleet of 45 urban public transport vehicles operating in Bratislava, Slovakia. Measurements were performed using a calibrated broadband isotropic analyser (Narda EHP-200A) at three longitudinal positions (front, centre, rear) in trams (n = 20), trolleybuses (n = 15), and internal combustion engine (ICE) buses (n = 10), during both steady-running and start-up operational phases. The dataset supports a dosimetric assessment of IF electromagnetic field exposure in passenger micro-environments generated by solid-state IGBT-based traction converters. It includes measured magnetic flux density values (μT), vehicle type, measurement position, and operational phase. All measured values were found to be in full compliance with ICNIRP 2010 and IEEE C95.1-2019 general public reference levels. This dataset accompanies the original research article submitted to Environment International (Trnka et al., 2026).
