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

摘要

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 e
