The subjects sat in a small van driven back and forth along a 2 km segment of a public straight road (in Eastern Finland) about 30 km distance from the transmission tower. Simultaneously, the radio signalling was recorded.
12 test runs were performed (six towards west and six towards east). Four electrosensitive subjects were tested at one time.
Exposure duration: continuous
|electric field strength||1 mV/m||minimum||measured||-||-|
|electric field strength||10 mV/m||maximum||measured||-||-|
|magnetic flux density||51.2 µT||minimum||measured||-||in the test area|
|magnetic flux density||51.8 µT||maximum||measured||-||in the test area|
|magnetic flux density||50.8 µT||-||measured||-||in the center of the geomagnetic anomaly area|
Involuntary hand movements of the subjects correlated with the electromagnetic field, i.e. with the FM radio wave intensity measured. The subjects reacted also on the place of a geomagnetic anomaly crossing the road, which was found on the basis of these recordings and confirmed by the public geological maps of the area.
The authors conclude, that radiofrequency exposure seems to affect the human hand reflexes of electrosensitive persons in a moving van along a normal public road which may have significance in traffic safety.
