Research and assessment of safety distance of TV electromagnetic fields
Santrauka
The evaluation covers the strengths of electric field and magnetic flux denstiy measured in frequency ranges of 5 Hz–2 kHz and 2–400 kHz of selected TV sets. The dependence of the electromagnetic field on the distance is addressed with reference to ergonomics and safety. Ten TV sets (5 tube and 5 LCD) were measured. There were 16 measurements for each one. The aim was to evaluate electric field and magnetic flux denstiy versus the distance from the tested device with regard to exposure levels. In addition, the distance and the strengths of electric field and magnetic flux denstiy emitted by tube and LCD TVs were compared. The results are presented in charts.
