ABSTRACT:
An instrument for monitoring the hazard arising from electro-magnetic (electric and/or magnetic) radio-frequency fields comprising an electric and/or magnetic field probe, a radio-frequency converter for converting the signals picked up by the probe into continuous current electric signals, a comparator for comparing the continuous current electric signals with predetermined reference values, and output indicators activated by the output signals of the comparator. Preferably the reference values divide the values of the field levels into three contiguous zones, respectively-of insignificant risk, of possible risk and of certain risk.
