Electromagnetic waves can cause undesirable effects on human body. These hazards have forced the related certification bodies such as ICNIRP and IEEE to propose standard limitations on the electromagnetic field levels. However, the current recommended procedures demand to verify the safety compliance of each measurement point based on a lengthy and impractical 6-minute averaging, in addition to spatial averaging, which complicates the procedure of RF dosimetry. Our statistical analysis on the performed experimental indoor and outdoor measurements show that lower time interval of measurements, such as 30 seconds and 60 seconds, predicts the same results in common electromagnetic environments, affected by wireless networks and broadcasting signals. The overall observed difference between 30-second and 6-mintue averaging time length from our reference value is less than 50% respectively in 13.5% and 10% of times, illustrating that there is not a significant difference between 30-seconds and 6-minute averaging. This makes the RF dosimetry procedure much faster, and cheaper while keeping it almost as reliable as before.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
