  • Title: Comparison of electric field exposure measurement methods under power lines.
    Author: Korpinen L, Kuisti H, Tarao H, Pääkkönen R, Elovaara J.
    Journal: Radiat Prot Dosimetry; 2014 Jan; 158(2):221-3. PubMed ID: 23960243.
    Abstract:
    The object of the study was to investigate extremely low frequency (ELF) electric field exposure measurement methods under power lines. The authors compared two different methods under power lines: in Method A, the sensor was placed on a tripod; and Method B required the measurer to hold the meter horizontally so that the distance from him/her was at least 1.5 m. The study includes 20 measurements in three places under 400 kV power lines. The authors used two commercial three-axis meters, EFA-3 and EFA-300. In statistical analyses, they did not find significant differences between Methods A and B. However, in the future, it is important to take into account that measurement methods can, in some cases, influence ELF electric field measurement results, and it is important to report the methods used so that it is possible to repeat the measurements.
