Human Exposure to Radiofrequency Electromagnetic Fields and Reassessment of FCC Radiofrequency Exposure Limits and Policies

In this document, the Federal Communications Commission (Commission) amends its rules related to the two methods that may be used for determining and achieving compliance with the Commission's existing limits on human exposure to radiofrequency (RF) electromagnetic fields: Exemption--consideration of whether a particular device or deployment is so clearly compliant, based on criteria in the Commission's rules, that it qualifies as exempt from the requirement to undertake a more thorough RF exposure analysis--and evaluation--a more specific examination of an individual site or device, which considers factors beyond those utilized for exemption and may be performed with a variety of computational and/or measurement methodologies. It also amends the rules related to an increasingly important part of demonstrating and maintaining RF exposure compliance: mitigation--the restriction from or limitation of RF exposure in controlled areas to keep RF exposure within the Commission's established limits by, for example, using signs or barriers. The amended rules are intended to provide more efficient, practical, and consistent RF exposure evaluation procedures and mitigation measures to help ensure compliance with the existing RF exposure limits. The amended rules replace the various inconsistent service-specific criteria for exempting parties from performing an evaluation to demonstrate compliance with the RF exposure limits with new, streamlined criteria. The amended rules also allow the use of any valid computational method to determine potential RF exposure levels, remove the minimum evaluation distance requirement for frequencies above 6 GHz, and establish post-evaluation RF exposure mitigation procedures (e.g., signage), to help ensure that persons are not exposed to RF emissions in excess of the existing limits. The Commission also affirms its prior decision to classify the pinna (outer ear) as an extremity in RF exposure compliance testing, finds no appropriate basis fo
