Abstract :
Prolonged urban measurements of electromagnetic field strength show oscillations undetected when using a 6´ interval. A wavelet analysis of long time series, unveils cyclic power changes, mainly of 24 h period. This shows that people are exposed to fields, the power of which is modulated at very low frequencies.
