What three overlapping areas are potential emf hazards separated into?

Potential electromagnetic field (EMF) hazards are typically categorized into three overlapping areas: electric fields, magnetic fields, and radiofrequency fields. Electric fields arise from voltage sources, magnetic fields are generated by current flow, and radiofrequency fields are associated with wireless communications and broadcasting. Each of these areas can contribute to exposure risks depending on the intensity and duration of exposure. Understanding these categories helps in assessing and mitigating potential health impacts from EMF sources.
