Measurement and Method in Radiofrequency Radiation Exposure Assessments

Radiofrequency radiation dosimetry describes how this radiation is being absorbed in the body. The basic units of measuring the radiofrequency exposure are the electric E (V/m), magnetic B (A/m) field strength, the power density S (W/m 2 ), and the Specific Absorption Rate (SAR) (W/kg). Many studies have made use of different types of instruments to assess the level of radiofrequency radiation exposure in an environment, and these types of equipment are either broad band meters or narrow band meters (spectrum analyzers). Different procedures or methods are used in radiofrequency radiation assessment, both in instrumentation and in measurement. From different studies, radiofrequency assessment methods are based on the study area of the studies, sampling time considered for the study, exposure distance relationship, the need for preliminary investigation and the choice of making use of a theoretical approach to the study.
