Real versus Simulated Mobile Phone Exposures in Experimental Studies

Abstract

We examined whether exposures to mobile phone radiation in biological/clinical experiments should be performed with real-life Electromagnetic Fields (EMFs) emitted by commercially available mobile phone handsets, instead of simulated EMFs emitted by generators or test phones. Real mobile phone emissions are constantly and unpredictably varying and thus are very different from simulated emissions which employ fixed parameters and no variability. This variability is an important parameter that makes real emissions more bioactive. Living organisms seem to have decreased defense against environmental stressors of high variability. While experimental studies employing simulated EMF-emissions present a strong inconsistency among their results with less than 50% of them reporting effects, studies employing real mobile phone exposures demonstrate an almost 100% consistency in showing adverse effects. This consistency is in agreement with studies showing association with brain tumors, symptoms of unwellness, and declines in animal populations. Average dosimetry in studies with real emissions can be reliable with increased number of field measurements, and variation in experimental outcomes due to exposure variability becomes less significant with increased number of experimental replications. We conclude that, in order for experimental findings to reflect reality, it is crucially important that exposures be performed by commercially available mobile phone handsets.

Main findings

The authors argue that real-life emissions from commercially available mobile phones are variable and differ substantially from simulated, fixed-parameter emissions used in many experiments. They state that experimental studies using simulated emissions show strong inconsistency (with less than 50% reporting effects), whereas studies using real mobile phone exposures show nearly 100% consistency in reporting adverse effects, and they conclude experiments should use commercially available handsets to better reflect real-world exposure.
