This article reports the outcome of a study commissioned by the Radiation Safety Unit, Govemment of Saskatchewan, which addressed the public concern on exposure to low-frequency electromagnetic fields (EMFs) surrounding power lines.

Measurements of EMF are reported for 14.4 to 230 kV power lines utilizing a model HI-3600-02 extreme low frequency (ELF) power frequency EMF survey meter.

Field intensities were within the Canadian standards, with the recorded value for a 230 kV/230 kV line voltage yielding a maximum electric field of 1,790 V/m at 15 feet from the center and a maximum magnetic field intensity of 2,376 mA/m at 25 feet from the center.

Continued research and analysis are required in determining the mechanism of interaction between EMFs and the human body and to determine if there exists a correlation between EMF exposure and health.
