FCC Policy on Human Exposure to Radio Frequency Electromagnetic Fields
The FCC is required by the National Environmental Policy Act of 1969, among other things, to evaluate the effect of emissions from FCC-regulated transmitters on the quality of the human environment. Several organizations, such as the American National Standards Institute (ANSI Opens in New Window), the Institute of Electrical and Electronics Engineers, Inc. (IEEE Opens in New Window),and the National Council on Radiation Protection and Measurements (NCRP Opens in New Window) have issued recommendations for human exposure to RF electromagnetic fields. On August 1, 1996, the Commission adopted the NCRP's recommended Maximum Permissible Exposure limits for field strength and power density for the transmitters operating at frequencies of 300 kHz to 100 GHz. In addition, the Commission adopted the specific absorption rate (SAR) limits for devices operating within close proximity to the body as specified within the ANSI/IEEE C95.1-1992 guidelines. (See Report and Order, FCC96-326) The Commission's requirements are detailed in Parts 1 and 2 of the FCC's Rules and Regulations [47 C.F.R. 1.1307(b), 1.1310, 2.1091, 2.1093]. The potential hazards associated with RF electromagnetic fields are discussed in OET Bulletin No. 56, "Questions and Answers About the Biological Effects and Potential Hazards of Radio frequency Electromagnetic Fields."
sort byFCC Advances Procedures on RF Safety Rules: On March 27, 2013, the FCC voted to advance its review of its various rules pertaining to the implementation of the National Environmental Policy Act (NEPA) requirements related to radiofrequency (RF) emissions from radio transmitters. The FCC has divided this process into three parts: a Report and Order (Order) and a Further Notice of Proposed Rulemaking (Further Notice) in ET Docket No. 03-137, and a Notice of Inquiry (Inquiry) in a new docket, ET Docket No. 13-84. In the Order the FCC concludes several technical and semantic issues initiated in 2003 that revise and update its regulations implementing NEPA. In the Further Notice the FCC proposes to further update and revise its procedures beyond its 2003 proposals. In the Inquiry the FCC requests comment to determine whether its RF exposure limits and policies need to be reassessed. Since consideration of the limits themselves is explicitly outside of the scope of ET Docket No. 03-137, the FCC opens a new docket, ET Docket No. 13-84, with the Inquiry to consider these limits in light of more recent developments. The Inquiry is intended to open discussion on both the currency of our RF exposure limits and possible policy approaches regarding RF exposure. While the FCC has continuously monitored research and conferred with experts in this field, and is confident in its RF exposure guidelines and the soundness of the basis for its rules, it is a matter of good government to periodically reexamine regulations and their implementation. The FCC looks forward to developing a complete record by soliciting the input of qualified expert agencies and organizations and the public, to determine whether the current rules and policies should remain unchanged, or should be relaxed or tightened.

Human Exposure to RF
- Radio frequency Energy FAQs This section contains answers to the most frequently asked questions receive d by the Commission concerning RF fields and their application. Also, see OET Bulletin 56 and the following brief addendum (added in September of 1997) regarding guidelines for evaluating human exposure.
- Update for Information On Human Exposure To Radiofrequency Fields From Cellular Radio Transmitters
In 1996, the FCC adopted updated guidelines for evaluating human exposure to radiofrequency (RF) fields from transmitting antennas such as those used for cellular radio. The new guidelines for cellular base stations are identical to those recommended by the National Council on Radiation Protection and Measurements (NCRP) discussed on page 2 of the FCC information sheet. These guidelines are also essentially the same as the 1992 guidelines recommended by the American National Standards Institute and the Institute of Electrical and Electronics Engineers (ANSI/IEEE C95.1-1992), also discussed on page 2, for operating frequencies above 1500 MHz. The FCC adopted guidelines for hand-held RF devices, such as cellular telephones, that are the same as those recommended by the 1992 ANSI/IEEE guidelines, discussed on page 4 of the information sheet.
