Plain English Summary
Researchers exposed rabbit ears to radiofrequency radiation at different power levels for 20 minutes, measuring temperature changes with and without blood flow. They found that normal blood circulation effectively prevented heating at exposure levels matching current safety limits (2 W/kg for the public, 10 W/kg for workers), but when blood flow was blocked, even the lowest exposure level caused temperature increases. This demonstrates that living tissue's natural cooling mechanisms are crucial for protecting against RF heating effects.
Study Details
The aim of this study is to investigate Role of blood flow on RF exposure induced skin temperature elevations in rabbit ears.
In this in vivo study, we measured local temperature changes in rabbit pinnae, which were evoked by ...
The results showed: (1) physiological blood flow clearly modified RF induced thermal elevation in th...
Our results demonstrate that the physiological effects of blood flow should be considered when extrapolating modeling data to living animals, and particular caution is needed when interpreting the results of modeling studies that do not include blood flow.
