Radiation Safety Plan

• Recommended by OSHA
• Elements of Plan
• Site Specific Issues
• Personnel Training
• Safety Procedures
• Definition of Controlled and Uncontrolled Area
• Installation of Signage
• Medical Monitoring of Personnel

2
Radiation Safety Training

• Principles of RF Radiation
• Safety Standards
• Harmful Effects
• Prediction and Measurement Techniques
• Recognition of Potential Hazards
• Human Protection and Mitigation
• Site Specific Radiation Issues

3
RADHAZ Mitigation Techniques

• Training of Site Personnel
• Proper Signage
• Marking of Areas Where Levels gt MPE
• Interlocks of Areas Where Levels gt MPE
• Personnel Warning Devices
• Protective Clothing
• Build Shielding or RF Barriers

4
Radiation Zone Description

• Controlled Zone
• Workers Assigned to Telecommunication System
• Personnel Have Knowledge of Radiation
• Less Stringent Requirements
• Uncontrolled Zone
• General Public
• No Knowledge of Radiation Conditions
• More Stringent Requirements

5
Radiation Hazard Signs

• Types, Placement and Design
• ANSI 95.2 - 1982
• Designations
• Notice, Caution, Warning
• Placement
• Property Boundaries
• Fences
• Buildings
• Towers

Radiation Safety Guidelines

• Develop a Site Specific RF Radiation Safety Plan
• Train All Site Personnel on RF Radiation Safety
  Issues
• Perform Radiation Safety Evaluations
• Periodically (yearly)
• Or, After Site Equipment or Structures Change

• Transition Period for New Rules

10
Radiation Safety Criteria

• Remains the Same But
• SAR will be included in Limit Tables
• Categorical Exclusion Rules Redefined
• Clarification or Expansion of Rules

11
Categorical Exclusion Rules

• Function of Separation Distance
• Testing Required for Tx Ant within 3 meters of
  Public
• Exception Given for Micro Base Stations
• Same Rules Applied for All Classes of Services
• Rules Based on Tx Power, Frequency and Proximity
• Height of Antenna No Longer Included
• Separation Distance Instead of Antenna Height

12
Evaluation of Mobile and Portable Devices

• SAR Evaluation for Part 15.247 Devices if They
  ARE
• Used within 20 cm of the Body
• Peak Power Exceeds 100 mWatts
• Transmitter Modules
• Host Independent

Compliance Procedures for Workers

• Worker is Adequately Informed
• Trained with Written and Verbal Material
• Aware of Mitigation
• Knowledge to Protect himself and Public
• Signage
• Site Has Appropriate Signs
• Controlled and Uncontrolled Areas Defined
• Labels
• Applied to Portable and Mobile Devices
• Proper Training on Use of Device

14
Labeling and Sign Requirements

• Define Consumer Products Needing Labels
• Fixed, Portable and Mobile Requirements
• Rules for Exclusion Rules for Labels

• Whole Body SAR

16
Spatial Averaging and Peak Levels in Near Field

• Applies to Fixed, Portable and Mobile devices
• Hot Spots Where SAR Partial Body Limits Apply
• Multiple Emitter Affects
• Near Field Variations
• Peak Hold Procedure in Lieu of Spatial Averaging
