There are literally thousands of studies examining the effects of electromagnetic fields (EMF). Many of these are designed to advance scientific understanding of how technological devices work, and in turn, to improve their functioning. Far fewer studies have been devoted to the effects of EMFs on the human body. This is unfortunate given the widespread use of cellular phones and the potential for toxic radiation effects.

Different Research Methods, Different Findings

As the use of microwaves, wireless routers, and cellular phones has increased, researchers have attempted to explore how EMF radiation may impact the human body. There are many approaches to this line of research, including experimental designs with rats and microanalysis at the cellular level. To date, most research with rats (chosen because of biological similarities to humans) has revealed no adverse biological effects following exposure to EMF radiation.

However, research at the cellular level has produced more equivocal findings. Specifically, some studies indicate cellular alterations, and in rare cases, cell atrophy or cell death, following exposure to deleterious substances such as EMF radiation. This mixed pattern of findings underscores the need for further research in the area.

One thing that will be especially important for advancing our understanding of EMF effects is research on human populations. Longitudinal epidemiological studies are needed to shed light on the links between low-level radiation exposure and poor health. It is an expensive and difficult undertaking, but one that is of paramount importance given the widespread use of EMFs.
