Question: I live 100 yards from an electrical substation. Do I have an increased risk of developing cancer?
Answer: The scientific evidence suggesting that EMF exposures associated with power-line frequencies pose any health risk is weak. EMF exposures in and around substations can vary greatly depending on factors such as the number of customers served via the substation and the pattern of distribution lines coming into and out of the substation. Since fields drop rapidly with distance, EMF exposures 100 yards from the substation would be much weaker than at the substation. If you are interested in knowing more about the EMF exposures around electric power equipment, you may want to contact your local electrical utility company.
