Tiivistelmä

The aim of the study was to analyze all values of electric currents from measured periods while performing tasks in forest clearing. The objective was also to choose and analyze measurement cases, where current measurements successfully lasted the entire work period (about 30min). Two forestry workers volunteered to perform four forest clearing tasks under 400kV power lines. The sampling frequency of the current measurements was 1sample/s. The maximum values of the current densities were 1.0-1.2mA/m2 (calculated internal EFs 5.0-12.0mV/m), and the average values were 0.2-0.4mA/m2. The highest contact current was 167.4μA. All measured values during forest clearing tasks were lower than basic restrictions (0.1V/m and 0.8V/m) of the International Commission on Non-Ionizing Radiation Protection. Bioelectromagnetics.
