ELECTROMAGNETIC-FIELD HEALTH-EFFECTS - AN ISSUE FOR DEVELOPING-COUNTRIES

Effects of small electromagnetic fields have been reported in cultured cells, laboratory animals, and humans. From the available data, we co nclude that EMF exposures associated with the distribution of electric power are likely to elicit responses in biological systems. However, cautious interpretation is needed because there are many inconsistenci es in the results. Even the more widely accepted observations (e.g., s uppression of nighttime melatonin) have not been entirely reproducible . Conclusive, repeatable observations, as well as clarification of the basis for these effects, are still needed. Furthermore, even if real, the observed effects are not necessarily causally linked to increased cancer fisk or other health hazards. However, the mounting body of la boratory data are consistent with possible health effects of EMF expos ure as suggested by the epidemiologic studies.
