Guidelines and Standards
From the EMF RAPID Program's Questions and Answers About EMF:
"In the United States, there are no federal standards limiting occupational or residential exposure to 60-Hz EMF.
At least six states have set standards for transmission line electric fields; two of these also have standards for magnetic fields. In most cases, the maximum fields permitted by each state are the maximum fields that existing lines produce at maximum load-carrying conditions. Some states further limit electric field strength at road crossings to ensure that electric current induced into large metal objects such as trucks and buses does not represent an electric shock hazard.
From the California Department of Health Services' Fact Sheet Electric and Magnetic Fields:
"Lack of understanding has kept scientists from recommending any health-based regulations. Despite this, several states have adopted regulations governing transmission line-generated magnetic fields at the edge of the “right-of-way” (“ROW,” the area immediately surrounding powerlines left clear for access for maintenance and repairs) because of concern about the risk of electric shock from strong electric fields present in these areas… All current regulations relate to transmission lines; none govern distribution lines, substations, appliances or other sources of electric and magnetic fields." (p.7)
So far, in the absence of conclusive scientific evidence, there is no sufficient basis for enacting laws or regulations to limit people’s exposure to EMF, so it is up to individuals to decide what avoidance measures to take, based on the information available." (p.8)
