Comparison between two power-frequency electric-field dosimeters.
Two instruments, an EFEM meter and a BE-log meter, have been tested on people working in switchyards for voltages between 70 kV and 400 kV. The results from the BE-log meter correlate well with the short circuit currents through people connected to the ground. The EFEM meter showed lower measured doses than the BE-log meter, and the relation between the two instruments was around 0.6.
