    "summary": "This systematic review summarizes occupational radiofrequency (RF) EMF exposure measurements from peer-reviewed publications and grey literature and compares reported maxima with occupational exposure limits. It reports that maximum exposures exceeding limits occurred for several workplace sources (e.g., dielectric heating, security/RFID scanners, plasma devices, and broadcasting/telecommunication transmitters), while exceedances were rare for microwave heating and radar. The review also notes case reports of occupational accidents with medical investigations of thermal health effects, often involving maintenance personnel.",
    "key_points": [
        "The review targets workplaces where high RF EMF exposures are possible, including broadcasting, telecommunication, security/identification, remote sensing, and industrial heating/drying.",
        "A systematic search was conducted in PubMed and Scopus, with additional grey literature identified via web searches.",
        "For each included publication, the highest measured electric field strength, magnetic flux density, or power density was extracted.",
        "Maximum exposures exceeding occupational limits were reported for dielectric heating, security/RFID scanners, plasma devices, and broadcasting/telecommunication transmitters.",
        "Exceedances of limits were reported as rare for microwave heating and radar applications.",
        "Some included publications were case studies of occupational accidents followed by medical investigation of thermal health effects, often involving maintenance personnel.",
        "The review highlights that emerging sources (e.g., fifth-generation telecommunication systems and energy transition technologies) may require further exposure assessment."
