Magnetic resonance equipment, diathermy and hyperthermia equipment, and electrosurgery equipment are the main sources of electromagnetic radiation in the medical industry. The medical staff using that equipment or working in nearby spaces are exposed more intensely than patients or people who are passing through, and so exposure within the radius of influence of that equipment must be evaluated and controlled. This includes measurements at low and high frequencies using the suitable devices and probes with isotropic response and RMS. The applicable standard is IEC 60601.
