(exposure assessment/dosimetric study)
Electrical wiring configurations and childhood cancer.
Published in: Am J Epidemiol 1979; 109 (3): 273-284
Aim of study (acc. to author)
Magnetic field exposure was assessed by wire- code configuration estimated for the birth and death addresses of the children. Three types of homes were considered to have high- current configurations: homes less than 40 m from large-gauge primaries or an array of six or more thin primaries; homes less than 20 m from an array of 3 - 5 thin primaries or from high-tension (50 - 230 kV) wires; and homes less than 15 m from first span secondary (240 V) wires. Endpoint/type of risk estimation
Type of risk estimation:
end poles: very low current
low-current configurations except end poles: low current
other high-current configurations: high current
substation: very high current
