title: Evolving perspectives on the exposure risks from magnetic fields.
abstract: Based on information from suggesting effects of positive and negative polarity on cancer cells, surveys were performed on magnetic resonance imaging devices, as well as other types of equipment capable of producing appreciable magnetic fields. These surveys were performed in areas where there was a potential for both occupational and general public exposure.
