Title Survey of electric and magnetic fields at Ontario hydro VDU work stations
Bibliographic information Ontario Hydro Research Division, 800 Kipling Ave., Toronto, Ontario M8Z 5S4, Canada, 1 Mar. 1984. 18p. Illus. 6 ref. Appendices.
Abstract This research report describes the methodology and instrumentation used in measuring electric and magnetic fields produced by VDTs at 54 different workstations. The frequency range investigated went from d.c. to a.c. beyond 1MHz. At 30cm from the VDT, the maximum equivalent environmental d.c. field was 1500V/m and the electric and magnetic fields at 17kHz were respectively 2.7V/m rms and 0.16A/m rms. These levels are thought to be too low to present a biological risk to the operators.
