ABSTRACT

This chapter focuses on sensors that are commonly used in measurements of static and low-frequency electric and magnetic fields and describes the radio frequency (RF) experimental dosimetry. Electric and Magnetic field sensors can be divided into vector component and scalar magnitudes types. Vector meters measure separately the three vector components of an electric and magnetic field. Total field or scalar meters measure the magnitude of the vector electric and magnetic field. Three orthogonal sensors are required to measure the components of the electric and magnetic field in all three dimensions. In order to estimate a potential health risk to general public and possible occupational hazards, extremely low-frequency (ELF) and RF fields should be quantified by measurements. Three types of electric field (EF) meters have been used to characterize ELF EF: free body meters, ground reference meters and electro-optic meters. The chapter explores the issue of RF field measurements and absorbed RF energy measurements.
