Factors influencing personal magnetic field exposure: preliminary results for power utility and office workers

摘要

Epidemiological studies and laboratory research suggest that exposure to extremely low frequency (< 300 Hz)magnetic fields is associated with an increase in risk of developing a number of rare diseases including leukaemia. Overall the risks to health appear to be smaller but a more accurate exposure assessment technique would help evaluate the true extent of any health effects. In this pilot study we aimed to identify and evaluate personal, work and environmental factors and their influence of measured exposure levels with a view to developing a method of reconstructing exposure. Office workers and power utility workers were studied using personal dosimeters to measure Magnetic field exposure, along with frequent observation or measurement of factors related to Exposure.
