Finland: FM radio en TV signalen veroorzaken spontane spierbewegingen.

Een interessante studie uit Finland die enerzijds de individuele gevoeligheid van verschillende mensen voor EM velden toont (electrohypersensitivity) en anderzijds een bevestiging geeft dat ''restless legs'' mogelijk samenhangt met zwakke elektromagnetische velden.

For testing human sensitivity to radio frequency (RF) standing waves a movable reflecting wall was constructed. Radio waves from the radio-TV tower reflected back and formed a standing wave near the reflector. When the reflector was moved, the position of the maximums of the standing waves changed and the electromagnetic intensity changed in the body of the standing test subject. The computer with an AD-converter registered the signals of the hand movement transducer and the RF-meter with 100MHz dipole antennas. A total of 29 adults of different ages were tested. There were 9 persons whose hand movement graphs included features like the RF-meter. Six showed responses that did not correlate with the RF-meter. There were also 14 persons who did not react at all. Sensitive persons seem to react to crossing standing waves of the FM-radio or TV broadcasting signals.
