RF safety compliance is both a regulatory requirement and an ethical responsibility. Understanding exposure limits and implementing appropriate safety measures protects workers and the public.
Exposure Standards
RF exposure limits are established by organizations including the FCC (OET-65), ICNIRP, and IEEE (C95.1). These standards define maximum permissible exposure levels based on frequency, with different limits for controlled and uncontrolled environments.
Exposure Assessment
Assessing RF exposure involves calculating or measuring power density and specific absorption rate (SAR) at locations where people may be present. Worst-case analysis ensures compliance under all operating conditions.
Mitigation Measures
When exposure levels approach limits, mitigation options include increasing antenna height, adjusting antenna tilt, reducing power, implementing exclusion zones, and installing RF warning signage.
Documentation
Comprehensive RF safety documentation supports regulatory compliance and demonstrates due diligence. Site-specific safety plans, exposure assessments, and training records should be maintained and updated regularly.
