The test persons wore a portable ECG-monitor for 12 hours (8 a.m. to 8 p.m.) during work exposure. The same workers underwent a control monitoring after a mean of 10 days (8 a.m. to 8 p.m.). The control was performed after a mean of 12 h since the last exposure. During the control recordings, the workers were at home.
|Setup||measurements were taken in the control booth of the locomotives at 0.1 m, 0.8 m, 1.3 m above the floor|
No significant differences in the ECGs between test person in exposure or control environment were found.
The data suggest the absence of extremely low frequency electromagnetic field influence on cardiac arrhythmia risk.
