Summary:
|
The concept of EMF is intangible, which often leads to apprehension and concern among the general public. To address these issues effectively, it is essential to adopt an objective and scientific approach to EMF and its exposure assessment. This helps build public confidence in the assessment process and plays a key role in dispelling misconceptions. EMF exposure assessment is a fairly elaborate process, which entails calculations, measurements, extrapolations of results etc. EMF exposure measurement is one of main aspects of the overall assessment framework. Measurement requires different types of EMF measurement equipment based on the scope and type of measurement, RF technologies deployed in the environment, frequency bands of operations etc.
To ensure accurate, reliable, and traceable measurements from EMF measurement equipment, calibration of such equipment is essential. This process involves comparing the equipment’s readings to a known standard, under controlled laboratory conditions. Typically, calibration includes assessing the frequency response, sensitivity, linearity, and isotropy of the measuring device. Equipment such as broadband EMF measurement equipment or spectrum analyzers are exposed to calibrated EMF sources (e.g., signal generators and antennas) at known field strengths and frequencies across the instrument's operating range. Deviations are recorded and correction factors are applied or documented. Regular calibration, usually annually or as specified by the manufacturer or regulatory requirements, is crucial for applications in occupational safety, environmental monitoring, and compliance testing.
Recommendation ITU-T K.calibr focuses on guidelines for calibration of equipment used for EMF exposure assessment (field measurements) from telecom installations such as IMT base stations etc. This includes types of equipment used for EMF exposure assessment and the methodology of their calibration, parameters that are calibrated, guidance on the infrastructure for carrying out calibration, standards available for calibration, measurement uncertainty, calibration periodicity and other relevant considerations.
