Categorical Exemptions
to Routine RF Radiation Evaluations
With it's August 27, 1997
Second Memorandum and Order, the FCC has adopted a sliding scale for
categorical exemption to routine RF radiation compliance testing based on peak
envelope power (PEP) at various Amateur Radio operating frequencies. While the
RF radiation exposure compliance levels are based on
average power, the categorical exemptions from the
requirement for periodic station compliance testing are based upon peak
envelope power (PEP). Stations operating at or below these respective PEP
levels are categorically excluded from having to perform a routine RF
radiation evaluation. However, all stations, regardless of
power level, still must comply with the RF exposure limits.
Please consult FCC
OET Bulletin No. 65 for more details on the exemption.
Another great source for information is the ARRLWeb's
RF Safety page.
