Abschätzung
- Fragebogen: Berufstätigkeit mit Berufsbezeichnung, Industriezweig, Beginn und Ende, Art der Beschäftigung (z.B. Vollzeit, Teilzeit, Saison) für alle jemals mindestens sechs Monate lang ausgeübten Tätigkeiten; detaillierte Fragen zu Berufsbezeichnungen mit möglicher Exposition bei Magnetfeldern (Tätigkeit, Art und Größe der benutzten elektrisch angetriebenen Werkzeuge oder Geräte, mittlerer Abstand zum Gerät; Zeitdauer, die bei der Arbeit mit oder in der Nähe von elektrisch angetriebenen Geräten verbracht wurde)
- Job-Exposure-Matrix: Anpassung der Expositions-Schätzer basierend auf den berufsspezifischen Fragebögen
