The Role of the Location of Personal Exposimeters on the Human Body in Their Use for Assessing Exposure to the Electromagnetic Field in the Radiofrequency Range 98-2450 MHz and Compliance Analysis: Evaluation by Virtual Measurements
Gryz K et al · 2015
Body-worn exposimeters showed errors from −96% to +133%, and even waist or chest placement left uncertainty higher than spot measurements.
Plain English Summary
Researchers modeled personal exposimeters measuring electric fields from 98–2450 MHz using a human body model and finite integration technique software. Calculations with 256 exposure scenarios showed the human body causes measurement errors from −96% to +133% compared to unperturbed fields. Placing a single exposimeter on the waist to the back side of the human body or on the front of the chest reduces the range of exposure assessment uncertainty across various conditions. Uncertainty using a single exposimeter remains significantly higher than spot measurements of unperturbed fields.
Why This Matters
For compliance testing, discrepancies can be compensated by applying a correction factor to measurement results or to exposure limit values. Applying a correction factor to either the measurement results or the exposure limit values can improve exposimeter use in compliance tests.
