RF Exposure Measurements

The possible health effects associated with exposure to radio frequency fields have been studied for more than half a century and the only established adverse effect is heating of body tissue. To protect the public from harmful exposure, the FCC requires that its licensees comply with its published radio frequency exposure standards, found in Parts 1.1307 through 1.1310 of Title 47 of the Code of Federal Regulations. FCC exposure limits are based on voluntary standards published by the American National Standards Institute (ANSI) and the National Council on Radiation Protection and Measurement (NCRP). The FCC limits have large safety margins relative to the levels where effects are observed.

Our clients often ask us to verify compliance with FCC exposure rules when a broadcast, cellular or land mobile radio facility is constructed or modified. Our president, Jay Jacobsmeyer, is a licensed professional engineer and has been doing this type of work since 1982. Compliance verification is sometimes done through analysis, but often measurements are required. Pericle owns a specialized instrument called a broadband exposure meter which is designed specifically for this type of measurement.
