Title Acute effects of ELF electromagnetic fields: A field study of linesmen working with 400kV power lines
Bibliographic information Oct. 1989, Vol.46, No.10, p.729-737. Illus. 26 ref.
Abstract The aim of the study was to investigate the possible acute effects of exposure to electric and magnetic fields. 26 experienced linesmen were studied during 2 working days while performing simulated routine inspections of insulators on steel poles of a 400kV power line, alternately live and dead. Exposure to electric and magnetic fields was measured using personal monitoring instruments. The mean exposure for the working day was estimated to be 2.8kV/m (SD=0.35) and 23.3ÁT (SD=4.2). The possible effects of exposure were studied using a battery of 4 automated performance tests, EEG, a mood scale, and a questionnaire to assess subjective symptoms. Furthermore, blood samples were collected for each subject on 3 different occasions during each workday, in order to test for possible hormonal changes. No statistically significant differences were found that could be attributed to possible exposure to electromagnetic fields.
