Understanding EMF Health Research

The research in this database comes from the BioInitiative Report, a comprehensive review of the scientific literature on EMF health effects by an international working group of scientists, researchers, and public health policy professionals.

Studies are organized by the primary biological system or health outcome examined. Many studies investigate effects across multiple categories—for example, research on cell phone radiation might examine both neurological effects and DNA damage.

Each category page includes a synthesis of the research findings, the weight of evidence showing biological effects, and links to individual studies with full details.
