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

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

RADHAZ Mitigation Techniques Training of Site Personnel Proper Signage Marking of Areas Where Levels > MPE Interlocks of Areas Where Levels > MPE Personnel Warning Devices Protective Clothing Build Shielding or RF Barriers

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

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

FCC NPRM Radiation Safety June 26, 2003 ET#  No Change to Exposure Limits Set in 1996  Update Rules for Categorical Exclusion  Evaluation Procedures for Mobile and Portable devices  Modify Compliance Procedures for Workers  Labeling Requirements for RF Devices and Site Signs  Spatial Averaging for Localized Peak Conditions in NF  Rule Changes to Insure Accurate Evaluation Procedures  Medical Implant Transmitter Evaluations  Transition Period for New Rules

Radiation Safety Criteria Remains the Same But: *SAR will be included in Limit Tables *Categorical Exclusion Rules Redefined *Clarification or Expansion of Rules

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

Evaluation of Mobile and Portable Devices  SAR Evaluation for Part Devices if They ARE: –Used within 20 cm of the Body –Peak Power Exceeds 100 mWatts  Transmitter Modules –Host Independent Radiotelephones -- < 2mW Laptop computers screen -- < 200 mW Laptop computer keyboard -- < 10 mW PDAs -- telephone mode 1.6 W/kg, hand held 4.0 W/kg PDAs keyboard -- < 25mW  Multiple Transmitter Modules –Frequency –Power –Measurement, SAR or Power Density

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

Labeling and Sign Requirements  Define Consumer Products Needing Labels  Fixed, Portable and Mobile Requirements  Rules for Exclusion Rules for Labels  Site Sign Requirements

SAR vs. MPE  SAR Values to be Listed in Limit Tables  Hazard Evaluators may use MPE or –Partial Body SAR –Whole Body SAR

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

Medical Implant Communication Service (MICS)  Present Rules Inconsistent for MICS Tx –Present-Compliance by Measurement and Calculation –New-Compliance by Measurement or Calculation
