Physical units to report intensity of electromagnetic wave
Abstract
Overview
The study focuses on standardizing the measurement units for electromagnetic wave intensity, crucial in the context of electromagnetic field (EMF) exposure and its potential health risks.
Findings
- The study proposes using W/m2 (watts per square meter) as the standard unit for reporting the intensity of electromagnetic waves instead of V/m (volts per meter).
- It addresses the inconsistency in terms, advocating for "wave intensity" over "power flux density" to align better with physical principles.
- A quadratic relationship between the electric field and intensity is highlighted, emphasizing the need for conversion calculations when using V/m, hence recommending W/m2 for its direct measure of intensity.
Conclusion
The recommendation to use W/m2 aims to enhance the accuracy and uniformity of EMF exposure measurement, supporting clearer and more effective monitoring of potential health implications associated with EMF exposure.
