Define a radiological survey instrument

Reference no: EM13522937

A FM radio station broadcasts at a frequency of 89.7 MHz. (WCPE) How far away from the transmission antenna must you be in order to properly use a radiological survey instrument that measures in power density (mW/cm2) rather than electric or magnetic field strength at this frequency? (yes this is a classical station)
