Abstract There is some suggestion from epidemiological studies that exposure of children and adults to 5060 Hz magnetic fields may be associated with an increased Incidence of leukaemia brain tumours and other cancers The main evidence is in the form of an Increased number of children with cancer living in homes near high current configurations (power distribution lines within a given distance to the home) Although the results are variable they appear to

support an association which is less weak for brain cancer than leukaemia when estimated using wire codes Given the low risk ratios and the surrogate nature of the exposure assessment these studies need supporting evidence from the laboratory studies to be convincing

Acute exposure to extremely low frequency (ELF) electric and magnetic fields will result in the induction of electrical potentials and currents in the body which at high enough field strengths or flux densities will
