Abstract
The occupational exposure to electric and magnetic fields during various work tasks at seven 110 kV substations in Finland's Tampere region was studied. The aim was to investigate if the action values (10 kV/m for the E‐field and 500 µT for the B‐field) of the EU Directive 2004/40/EC were exceeded. Electric and magnetic fields were measured during the following work tasks: (1) walking or operating devices on the ground; (2) working from a service platform; (3) working around the power transformer on the ground or using a ladder; and (4) changing a bulb from a man hoist. In work task 2 “working from a service platform” the measured electric field (maximum value 16.6 kV/m) exceeded 10 kV/m in three cases. In the future it is important to study if the limit value (10 mA/m^2^) of Directive 2004/40/EC is exceeded at 110 kV substations. The occupational 500 µT action value of the magnetic flux density field (B‐field) was not exceeded in any working situation. Bioelectromagnetics 31:252–254, 2010. © 2009 Wiley‐Liss, Inc.
