In response to a request from the County Tax Administrator, an investigation was begun into exposure to electric and magnetic fields at the Cape May County Board of Taxation (SIC-7389), Cape May Court House, New Jersey. Employees there suspected they were receiving high exposure to extremely low frequency (ELF) electric and magnetic fields. Measurements were taken, with particular attention given to the areas around four large switchboards which were located directly behind the wall of the tax office. At the outside corners of the building and in the parking lot outside, the magnetic field levels ranged from 0.1 to 10.7 milligauss (mG). At similar locations, electric field levels ranged from 1.9 to 6.9 volts/meter (V/m). Inside the building, magnetic and electric field levels ranged from 0.1 to 900mG and 1.4 to 5.7V/m, respectively. Magnetic field levels measured in the vicinity of four administrative officials ranged from 3.02 to 33.55mG. Two of the four workers reported nonmalignant breast tumors; the other two reported thyroid conditions and an abnormal pap smear test result. All the measured levels were significantly below current occupational exposure limits. The authors conclude that all ELF electric and magnetic fields were below occupational exposure limits. It was not possible to determine whether any of the reported medical problems resulted from exposure to ELF.
