How Source Matching Works
Studies are matched to sources based on the frequency of electromagnetic radiation used in the research. For example, studies using 900 MHz - 2.7 GHz are associated with cell phones, while studies at 50/60 Hz relate to power lines and household wiring.
Many studies fall into multiple source categories when they use frequencies that overlap different devices. A study at 2.4 GHz, for instance, could be relevant to WiFi, Bluetooth, and microwave ovens.
Each source page shows the total number of matching studies and key findings specific to that type of EMF exposure.
